Let Your Guppy Swim Happily: The Beginner’s Guide to Poecilia Reticulata Care

The Poecilia Reticulata, a type of small fish native to South America and the Caribbean, was introduced to various other countries in past centuries in order to reduce mosquito populations. Although this method seemed promising, its efficiency is still undetermined. They are brightly colored, live-bearing freshwater fish belonging to the family Poeciliidae that are popular as pets in home aquariums.

Guppies are able to live in a wide range of pH levels and can endure highly polluted water, which may be found in channels ranging from shallow streams to open drains and urban canals. Males are generally far brighter in color than females and are somewhat smaller. The female fish do not lay eggs; rather, they give birth to live young. Guppies are highly favoured as aquarium fish as they are relatively easy to care for, do not grow too large and have a wide range of colors and patterns.

Poecilia Reticulata

Poecilia Reticulata Care

Guppies are livebearers and native to Caribbean islands and northern, tropical South America. Poecilia Reticulata natural habitat is slow-moving streams with plenty of vegetation. They are omnivorous feeding mainly on small invertebrates, detritus and occasionally fish eggs.

Guppies are not demanding fish when it comes to water quality and will tolerate a wide range of conditions. However, they will thrive and show their best colors in clean water with a neutral pH. Ammonia and nitrite levels should be zero, as these toxins can quickly kill fish. Nitrate levels should also be kept as low as possible. These fish can also withstand high temperatures and low oxygen levels.

To maintain guppies in optimal health, regular partial water changes are recommended. A well-balanced diet is a key to the success of keeping any fish healthy. While Guppies are not fussy eaters, a diet consisting mainly of live foods will bring out their best colors and encourage growth. A good quality flake or pellet food can be used as a staple diet, supplementing this with live foods such as brine shrimp, daphnia or bloodworms.

Guppies are social creatures and do best when kept in groups. A group of 5 or more is ideal, with the ratio of males to females being 2:1. If a group is not possible, then a minimum of 2 guppies should be kept together. When choosing your guppies, always try to select healthy-looking specimens with bright colors and clear eyes. Avoid fish that are pale or have clamped fins as these are signs of poor health.

Poecilia Reticulata Size 

Males can grow to 3 cm (1.2 in) long, while females can grow to 5.5 cm (2.2 in). Since they are small in size, they are ideal for smaller tanks and can even be kept in bowls.

Poecilia Reticulata Lifespan 

The average lifespan of guppies in the wild is approximately 2 years, though it can greatly vary. In captivity, however, with proper care and maintenance, they can live up to 3-5 years.

Poecilia Reticulata Appearance

Different guppy varieties can be distinguished by their colors and patterns, as well as the length and style of their tails. Tail type, color, and eye color are all key Poecilia Reticulata Characteristics used to categorize different types of guppies. The strain of P. reticulata bred in captivity may look very different from its Poecilia Reticulata Wildform, due to selective breeding for decoration and color. Domestic females may display color and patterns that are only seen in males, particularly in the caudal region, whereas wild caught specimens are grey/silver.

Fantails, flag tails, round tails, spire tails, and veil tails are just a few of the many Poecilia Reticulata classifications in terms of its tails. Some guppies have long, flowing tails, while others have short, flat tails.

Guppies come in a wide range of colors, including red, orange, black, yellow, green, pink, purple, silver, and blue. Spots and stripes are common guppy fish patterns that may be seen on their bodies, fins, and tails. Their tail fins are usually lengthy and have a flowing appearance. Natural Selection on color patterns in Poecilia Reticulata is complex, and often more than one factor is involved. The most notable distinction between male and female guppies is size: females reach about an inch longer than males when fully grown. Male guppies are more slender than female guppies, and males are generally more colorful while females are often duller in color.

When guppies are stressed, they become pale in color. Female guppies become rounder and paler than usual when they are breeding, with a black spot appearing behind their stomach. Male guppies colors become more vibrant when they are seeking a mate.

For the aquarium trade, brighter colors have been bred. The tail fin margin may be extended to form a small sword in males, but this is not as common as the enlarged fins seen in ornamental forms. In males, the anal fin is shaped into a gonopodium for sperm transfer. There is only one dorsal fin.

Poecilia Reticulata Behavior

Guppies are a calm species. They love being kept in groups and will stay together, especially when they're scared or during feeding time. The males are constantly chasing the females around and bending themselves into strange formations and wiggling their fins in an effort to impress them. They are active swimmers, you'll see them moving about all the time.

Guppy fish are intelligent creatures that will quickly learn where their food is located. They often react very strongly when someone comes near their aquarium. You may see a group of guppies flocking toward you when you enter an aquarium shop with a congested guppy setup. They'll chase a finger or hand if they think it's food!

Guppies are a lot of fun to keep. If you're an experienced fishkeeper, don't be dissuaded by their reputation as "beginner fish." They're not only entertaining to watch but also a great addition for any fishkeeper- regardless of experience level.

Poecilia Reticulata Feeding & Diet

Guppies in the wild are mainly insectivores, as revealed by their upturned mouth. These fish consume fallen insects as well as mosquito larvae, leading to many individuals throughout the world purposely introducing them in hopes of reducing local mosquito populations. If other food sources are running low, they will turn to eat algae.

The diet of the Guppy (Poecilia reticulata) is mainly based on live foods, but also accepts good quality flake or granulate. In terms of pellets or tablets, it is best to crush them before giving them to your fish, as guppies have small mouths. It is a very sociable fish and does not hesitate to eat in the presence of other fish, even those much larger than it. The recommended feeding for the good development of your guppies is 3 to 4 times a day with small meals that the fish can consume quickly. If you have fry, you will have to feed them more frequently because they need more energy to grow. As for the size of the pellets or flakes, they must be adapted to the size of your fish. If they are very small, use crushed tablets or flakes. If the pellets are too big, your guppies will have a hard time eating and could even choke on them.

Commercial guppy breeds are extremely adaptable and can feed on a wide range of foods. They also enjoy eating regular tropical fish food or guppy food, which is usually smaller and simpler for them to consume. Adding frozen foods like mosquito larvae to your diet is essential for maintaining a healthy and well-maintained diet!

Guppy fish consume zooplankton, insects, and detritus. They usually eat insects, but they've been seen eating: ceratopogonids, chironomids, culicids, dipterans, hemiopterans, and hymenopterans.

Poecilia Reticulata

Poecilia Reticulata Tank Mates 

Although they may occasionally nip at fish with longer fins (including other livebearers), these livebearers are typically docile and should only be kept with other calm species.

If you want to house your guppies with other fish, here are some good tank mates to consider:


Platies are another live-bearer species that can be kept with guppies. Platies, like guppies, breed rapidly as well. So expect a large number of small fish if you don't remove the fry from the tank.

When it comes to food, platies are not picky eaters. They will feed on flake food, frozen food, freeze-dried bloodworms, fruit flies, and mosquito larvae. Platies are a good option for beginners looking to start their first freshwater aquarium. A 20-gallon tank is the suggested size for keeping Guppy and Platies together.


Swordtails are live-bearing fish that breed abundantly and get along well with other live-bearing fish like guppies or platies, making them ideal for a wide range of water conditions.

Swordtails are one of the most popular fish kept as pets. Unlike other types of fish, they're simple to maintain. They like living in groups and enjoy doing so, but they aren't schooling fish. Just like guppies, they're omnivorous and feast on items such as flake food, mosquito larvae, brine shrimp, daphnia, etc.

If you're searching for a fish that's easy to care for and suitable as a buddy for your guppies, swordtails are one of the greatest choices. In order to keep Guppy and swordtails together, you will need a minimum 20-gallon tank.


Mollies are compatible tank mates for Guppy fish because of their similar size and temperament, but they can also get along with many other freshwater fish.

Molly fish are live-bearing, hardy fish that can flourish in both freshwater and saltwater aquariums. Mollies are omnivores and will eat anything from frozen, live, dried food to vegetables.

Mollies are a good choice for first-time fishkeepers. They're easy to care for and can be kept in a wide range of water conditions. Male and female mollies may be kept together without much effort, as they breed quickly and require little management on your part.

Honey Gouramis

Since Honey Gouramis are very high-maintenance, we do not recommend them for beginners. They enjoy the company of others and do best when living in a group, so a tiny tank is not ideal for them.

They also require planted tanks that provide them with lots of shade and plenty of hiding places. Aquarists typically use floating plants to provide them with the natural shaded environment in which they thrive. They're a quiet, docile species that make excellent pets for Guppy fish.

In the wild, they consume insects and their larvae, but in aquariums, they may eat anything from frozen to live foods.

Cory Catfish

Cory catfish come in a wide range of sizes and colors, but they're one of the simplest fish to maintain since they're both friendly and calm towards other species.

Cory Catfish are great for aquariums with guppies since they both occupy different parts of the tank and eat leftover food. Corys tend to stay at the bottom, which helps keep algae and muck from building up in the water.

Harlequin Rasboras

Harlequin Rasboras are another freshwater fish that are good for beginners and easy to care for. The most noteworthy characteristic of this species is its reddish-copper hue, which is further emphasized by a triangular-shaped patch on the back end of its body. You should keep them in groups of 8 to 12 because they school together and are very vibrant fish. When they are kept in small groups, they can become stressed or timid.

Harlequin Rasboras are mid-dwellers, which is the same level as Guppies, but there will be no territorial behavior or tension between them. The Harlequin Rasbora fish is not picky and will consume a variety of foods. For the best outcomes, ensure they have some form of each fresh, dried, frozen, or flake in their diet.

Bristlenose Pleco

The Bristlenose Pleco is a peaceful fish, making it the perfect tankmate for Guppies. As their name suggests, they can be identified by the fleshy tentacles sprouting from their head.

These fish spend most of their time near the bottom of the tank and prefer to eat algae. This is good news for you because it means they'll help keep your tank clean. Plus, they won't bother your Guppies since those fish tend to stay in the middle part of the tank.

They enjoy hiding places like roots, caves, and plants, and they'll forage in the substrate of your tank looking for a herbivore diet. However, they can't subsist on algae and scraps alone, so offer them spirulina wafers, granules, and veggies like lettuce or zucchini to supplement their diet.

In addition to being a popular fish for home aquariums, the Bristlenose Pleco is also a good beginner-friendly fish. They're hardy and don't have many specific needs, making them easy to care for.

Cardinal Tetra

Cardinal tetras are lively and colorful freshwater fish that are simple to care for. It's advisable to maintain them in groups of seven or more because they're schooling fish.

Cardinal Tetras and Neon Tetras are often confused because they look so similar, but there is one key difference. The red stripe on a Neon Tetra extends from the dorsal area (back) to the tail, whereas the red stripe on a Cardinal Tetra runs along the entire body of the fish.

The only time when Cardinal Tetras and Guppies can't peacefully coexist is when there are few hiding spots in the tank, as the Tetras might eat Guppy fry. If you do plan on keeping fry, ensure that there will be plenty of places for them to hide.

They're not fussy eaters; they'll consume both fresh and high-quality flake foods as well as frozen meals. Cardinal tetras are notoriously difficult to breed, and you'll need a separate breeding tank and stable water chemistry in order to do so.

Nerite Snails

Nerite snails are gentle, freshwater creatures that many people keep as pets due to their skills in consuming algae. If you're looking for an affordable way to keep the algae in your fish tank under control, then these snails are a great match for guppy fish. Because Nerite Snails require salt water to reproduce, you won't need to take any precautions to keep their population under control.

Purchase these snails from a reputable source, and check that the specimens are active and free of injuries. Look for snails that are affixed to the glass (those are the lively ones!) and keep away from those on the bottom of the tank that is motionless upside down.

They can adapt to many water conditions and do not need much care. As a result, these snails are low-maintenance pets that thrive in planted aquariums.

Otocinclus Catfish

The Otocinclus Catfish is a timid freshwater fish known for being an amazing scavenger and having an insatiable appetite for algae. This species is small, only reaching a maximum of 2 inches at maturity. They're also quite fast swimmers. In fact, you'll see them moving from one side of the tank to the other in seconds. If the water conditions are not ideal, these fish will not thrive. Oto Catfish need to supplement their diet with algae wafers and soft veggies since they can clean out a whole tank of soft green algae in less than 24 hours. If you choose to house them with Guppies, please observe them carefully as Guppies have been known to be nippy.

Kuhli Loach

These eel-shaped freshwater fish make great companions and get along well with a variety of other freshwater fish, including guppies. They like to be in groups of three to five, but they are mostly nocturnal, so you might not see much activity out of them during the day until they get used to your tank. The Kuhli Loach does best in an aquarium with lots of live plants and driftwood, a sand substrate, and clean water. Kuhli Loach doesn't grow much longer than 4 inches, so it's feasible to keep a school of Kuhli Loach in a 20-gallon tank. They prefer live foods but will consume any other form, including freeze-dried, frozen, wafers, flake food, and tablets, according to their dietary needs. If you own Kuhli fish, it's important to keep a close eye on them. If your tank isn't covered, they might jump out.

Red Cherry Shrimp

If you aren't only interested in fish for your tank, the Red Cherry Shrimp can be a fantastic addition to an aquarium with guppies. They're not picky, and even beginning aquarists can keep them. They breed fast, and they get along well with other fish of the same species.

Newborn shrimp are often eaten by fish, so typically it's not a good idea to mix fish with shrimp. Guppies can be an exception though, especially when Red Cherry Shrimp are involved because they reproduce quickly.

Red Cherry Shrimp thrive when they have a balanced omnivorous diet that consists of fresh vegetables (such as boiled zucchini and spinach) as well broad-spectrum processed foods like pellets, flakes, and specialized shrimp food.

I suggest you try adding Red Cherry Shrimp to your Guppy tank but also be sure to add extra hiding spots. If you don't, they'll rummage for food and enter places where they're not supposed to go.

Amano Shrimp

Although Amano Shrimp are larger than Cherry Shrimp. If kept with peaceful bottom-dwelling fish like guppies, they can coexist in a community freshwater tank. What makes them a difficult pet to keep is their larger size and how excellent they are at hiding, so much so that their owners may think they died. The coloring of Amano Shrimp varies depending on what they eat — if their diet consists only of fish food, they appear reddish, but if they consume algae and detritus instead, their shade turns green. They enjoy leftovers of fish food, but they require additional nutrition in the form of flakes, pellets, frozen, and live foods. They enjoy consuming vegetables like cucumber and squash, as well.

Crystal Red Shrimp

The Crystal Red Shrimp is a shrimp with a red and white striped body that stands out. They are difficult to breed, which is one of the reasons for their higher cost. If you feed your guppies well and give your shrimp many places to hide, you may be able to house them together. This is especially true because guppies are not natural predators.

African Dwarf Frog

If you want something other than fish and shrimp in your tank of Guppy fish, maybe you should consider adding a frog. Guppies occupy the middle layer of the aquarium while African Dwarf frogs reside at the bottom. The main disadvantage of keeping the two species together is feeding challenges. Because African Dwarf Frogs are slow eaters, it is necessary for aquarists to spot-feed them. However, this may be an issue for beginners. If you're not prepared to handle the challenges that come with owning a frog, it's probably best to avoid adding one to your fish tank.

Poecilia Reticulata

Poecilia Reticulata Tank Setup 

As with most freshwater fish, the guppy is a very adaptable creature that can live in a wide range of different tank setups. However, there are a few factors to consider when setting up a tank for your guppies so that they may thrive. Here are some things to keep in mind:

Tank size: A minimum tank size of 5 gallons is recommended for a trio of guppies since they typically grow to be 2 inches long. If you plan on keeping a larger number of guppies, or other fish species along with them, you will need a larger tank accordingly. A 10- or 20-gallon aquarium is more appropriate in the long run because they reproduce quickly.

Water Parameters: Guppies are tropical fish and prefer warm water. An ideal water temperature for guppies is between 74 and 82 degrees Fahrenheit. If your home is not naturally warm enough to maintain these temperatures, you will need to invest in an aquarium heater. A pH of 5.0-7.0 is also ideal for guppies.

Filtration: A good filtration system is essential for any aquarium, and this is especially true for a guppy tank since they are such prolific breeders. It is recommended to have a filter that can turn over the tank water at least 3-4 times per hour. It is preferable to use mild filtering, such as a sponge filter, to protect the tiny fry from being drawn up into the pump.

Decor: Guppies are not picky when it comes to decor and will do well in a variety of different setups. That being said, they do prefer some hiding places and vegetation in their tanks. live plants are a great option for guppy tanks, not only for their aesthetic value but also because they help to keep the water quality high. Hiding spots can help reduce stress levels and make them feel more secure in their environment. Driftwood, rocks, and caves are all good options for guppy hiding spots.

Lighting: Guppies do not require special lighting and can do well in a range of different light conditions. However, if you are growing live plants in your guppy tank, you will need to provide adequate lighting for plant growth.

Poecilia Reticulata Breeding

Guppies have a complex mating system called polyandry, in which females mate with multiple males many times. Guppies mature rapidly, and most are able to mate after two months of age. Male guppies mature in 7 weeks or less, while female guppies produce young at 10–20 weeks and continue to do so until they are 20–34 months old.

Multiple mating provides benefits to both genders; however, males gain more advantages from this system. Male guppies that mate more often have greater reproductive success, so they are motivated to court and mate as much as possible. Female guppies prefer certain males, especially those with brightly colored fins. Male guppies with orange spots on their flanks are more attractive to female guppies.

Males are usually smaller than females, with a brightly colored tail and fin. The anal fin has morphed into a gonopodium, which is used for internal fertilization. Males are constantly pursuing and mating with females. Females can keep sperm for future fertilization and may produce young every four weeks(The sperm can be kept by the female for up to a year.). This allows them to be more selective about when and with whom they mate. Females pregnant with offspring can be identified by the black triangle situated between the anal and pelvic fins. The incubation process takes approximately one month when the temperature is set to 23°C or 73°F. Females produce 20-40 live young after a gestation period. However, this duration can differ significantly depending on the temperature variation (anywhere from 3 to 5 weeks). There is no parental care, and parents may even prey on their children. If you want to keep the fry separate, use a second smaller and equipped aquarium and remove the female after birth.

So to sum it up, the issue won't be breeding, but rather overpopulation management!

Poecilia Reticulata Fry 

Fry is born fully functional and independent, complete with all its fins and color patterns. They will immediately start grazing on algae and any small invertebrates they can find in the tank. It is best to provide them with live food such as brine shrimp or daphnia to ensure they get the nutrients they need to grow.

As they grow, you can start to introduce them to flakes or pellets. However, it is important to remember that guppy fry is very small and needs very small food. You can either purchase commercial fry food or crush up regular fish food into a powder.

If you are keeping fry with their parents, you should offer them a lot of vegetation so that they can escape the appetite of their parents. Large-leafed plants or mosses like Riccia and Java moss going to the surface will do.

If you are keeping fry with their parents, you should offer them a lot of vegetation so that they can escape the appetite of their parents. Large-leafed plants or mosses like Riccia and Java moss going to the surface are good options. The fry will reach adulthood at around 3/4 months.

Poecilia Reticulata

Poecilia Reticulata Diseases

Guppies are relatively resistant to disease, but there are a few conditions to be aware of.

It is easier to prevent health problems than it is to cure sick fish. Here are some easy measures to avoid most illnesses:

  • Daily inspection of your fish is vital to their health.
  • Water parameters and temperatures should be maintained at the proper levels.
  • Maintain your aquarium on a regular basis, and make weekly partial water changes.
  • It's necessary to feed your fish, but too much food is detrimental.
  • Remove any dead fish from the tank as soon as possible.
  • Introduce new fish to your main display tank after a 3-4 week quarantine period.
  • If any of your fish become ill, transfer them to a hospital tank immediately.

Common Guppy Diseases & Treatment 

It's always simpler to cure guppy's illnesses if you have the right supplies on hand to medicate your fish at home. The following diseases can be deadly for your pet guppies:


Velvet disease is hard to spot early. If you see gold dust on your fish's body, they may have oodinium. This dust is barely visible to the human eye and often described as small dots. As a result, you must inspect your fish closely when doing check-ups. Another significant issue with this disease is that it spreads rapidly.

Seachem Cupramin is a copper medication that is the best cure for velvet. You should be aware that this chemical can harm snails and shrimp. Besides using the treatments above, another helpful way to manage your velvet is by turning off all lights. This will support the healing process and is something you should do as soon as possible. If your fish are recovering, you'll want to do frequent water changes to ensure that any symptoms don't linger.

White Spots – Ick

This is one of the most common ailments that all fish keepers are familiar with. As long as you offer adequate therapy and detect this “ick” in time, guppies rarely die from this illness.

Your fish will have white spots if they are sick with this illness. You may notice that your fish is bumping into objects or swimming near the tank's edge, which might be a clue it's ill. It's probably easier to spot the white spots, but you could also notice that your fish aren't as hungry as they were before.

In order to treat Ick, you'll need to do a few things. Here are the steps you should follow:

  • Quarantine your affected fish in a hospital tank.
  • Begin adding aquarium salt to your tank. Keep in mind that both tanks will need to be salted, not just the sick hospital tank.
  • Raise the temperature of the water to 80°F.
  • Treat with a recommended medication, such as Seachem ParaGuard.
  • Try to increase the percentage of water changes you normally do, and do them more frequently.

By following these steps, your fish will have fewer white spots and feel healthier overall. This process takes approximately one week; however, you may see results sooner.

Fin Rot/Tail Rot

Fin Rot is a bacterial infection. This can be a difficult problem to diagnose because sometimes the issue is due to water contamination and other factors. The first step is to quarantine the fish that are already sick. Put the sick fish into a hospital tank to protect the others in your aquarium.

After that, you should administer an antibiotic or Seachem ParaGuard to your fish. If your fish has this problem due to fungus or ammonia burns, it will require a different medication. Please keep in mind which medicines are appropriate for each illness.

Swollen Gills

Ammonia is the primary cause of this symptom. Ammonia is a hazardous substance to handle, and it can make guppies to try to breathe air on the surface of the water. Because fish waste is a common reason for this, you must check your aquarium on a regular basis to combat the condition. If your fish are gasping for air, it's a probable indication that the water quality is poor. It's important not to hesitate when performing a water change, and you should also do an ammonia test immediately. It's probably a good idea to limit how much you feed your fish while you're keeping track of all of your water checks.

Red Blood Spot Disease

This disease is easy to detect because of the red coloring. More often than not, red blood spots on fish are caused by stress from a new aquarium environment. Bacteria live in fish aquariums undetected, and they can have a significant impact on the fish's immune system, causing the fish to be more susceptible to disease. If you introduce too many fish into your aquarium at once, the bacteria won't have a chance to establish themselves and create a healthy environment for all of the fish. If you're adding fish in less than a month, you'll almost certainly encounter an issue like red blood spots as a result of poisoning.

If you see red blood spots on your fish, the best course of action is to remove the fish from the main aquarium and place it in a hospital tank. This will help to prevent the spread of disease and allow you to treat the fish more effectively. There are a few different treatments for red blood spot disease, and the most effective one will depend on the underlying cause. If the disease is caused by stress, the best thing you can do is to make sure that your fish are acclimated properly and that they have a good environment to live in. If the disease is caused by bacteria, you'll need to treat the aquarium with an antibiotic. Since you can't see ammonia or nitrate levels, you'll need a method to determine whether your water is suitable for fish or not. The Seachem Ammonia Alert is one of the most useful tools for monitoring water levels.

Columnaris & Mouth Fungus

Even though the name might make you think it, the fungus is not actually the culprit for this. Bacteria are to blame. This will be apparent in the fish's mouth, of course. There will be a vast white patch in the fish's mouth that signals this illness. Your fish may have trouble swimming as if it were disoriented. In addition, the fish will slowly eat less and less.

You need to regularly check your tank because this disease can turn deadly if left unchecked.

Formalin is one of the most popular chemicals for treating fish with mouth fungus. If not using formalin, then aquarium salt is almost certainly being used to cure the fish. It's still crucial that you do water changes, even when adding salt to the tank. The finest thing you can do after treating your fish for this illness is to maintain them in a healthy tank environment. If there are too many fish in one tank, it can lead to the reoccurrence of the disease. So you must keep an appropriate number of fish in each tank to protect them.


Dropsy is a deadly disease that makes your fish look bloated. This can prevent them from swimming properly and may cause other issues, like an infected kidney. This disease is very dangerous and by the time you see it, it will be too late to do anything about it. So be very careful to avoid this disease. Dropsy is caused by a lot of stress for an extended amount of time, so providing your guppy fish with a good living environment full of hiding places when they require it is critical. The best way to fight Dropsy is to keep the water clean and free of pollution.

Popped Eyes

Popped eyes are a condition that can happen to any fish, and it's pretty common in guppy fish. It happens when the pressure inside the eye becomes too much, causing the eye to pop out of its socket. This usually happens because of an injury or infection, but it can also be caused by malnutrition. Popped eyes can actually cause your fish to go blind. By treating your fish without understanding the underlying issue, you may do more harm than good. If you see a fish with popped eyes, the best thing you can do is to contact a veterinarian specializing in fish.

Swim Bladder Disorder

Swim Bladder Disorder is a condition that affects the swim bladder of fish. This can be caused by a variety of factors, including:

  • Incorrect water temperature
  • Poor water quality
  • Inadequate diet
  • Genetic disposition

If your fish is suffering from Swim Bladder Disorder, you will notice that it has difficulty swimming and may even float upside down.

If you suspect that your fish has Swim Bladder Disorder, you should take it to a vet or qualified aquarium professional for diagnosis and treatment.

Treatment of Swim Bladder Disorder will vary depending on the underlying cause. For example, if the disorder is caused by poor water quality, then improving the water quality will be the primary focus of treatment. Ammonia may also induce this condition, but it's typically due to the transfer of a fish from a shallow tank to a deep water tank.

Gill Flukes/Gill Worms

Gill flukes and gill worms are parasites that commonly affect fish. These parasites attach themselves to the gills of fish and can cause a variety of problems, including:

  • Difficulty breathing
  • Redness and inflammation of the gills
  • Excessive mucus production

If your fish is suffering from gill flukes or gill worms, you will notice that it has difficulty breathing and may be gasping for air at the surface of the water. The gills may also appear red and inflamed. When you put new fish into your tank without quarantining them, they can infect one another. So it's never a good idea to combine new fish or plants into your aquarium without quarantining them first.

If you suspect that your fish has gill flukes or gill worms, you should take it to a vet or qualified aquarium professional for diagnosis and treatment. Treatment of gill flukes or gill worms will generally involve using a medication that is specifically designed to kill the parasites. You may also need to do a water change and clean the filter to remove any parasites that may be present in the tank.

Camallanus Internal Worm

This is a worm that can sometimes be found in guppies. This is somewhat more prevalent in outside ponds. Indoor populations may encounter this infection on rare occasions, however, it is thought to be caused by feeding live cyclops. If you keep that in mind, you'll be free from this illness.

To cure this sickness, you'll need to make a lot of water changes and get your population back to a point where they can live well. In addition, you'll need to take the medication with a special medicine called Levamisole.

Hexamitiasis - Hole in Head/Body

This disease is characterized by raised circular lesions on the head and body of affected fish. The parasites that cause this disease are typically found in poorly maintained aquaria and can be introduced to a healthy aquarium via infected fish or live food. If your fish is suffering from Hexamitiasis, you will notice raised lesions on its body and head. These lesions may eventually become ulcerated and lead to secondary bacterial infections.

If you suspect that your fish has Hexamitiasis, you should take it to a vet or qualified aquarium professional for diagnosis and treatment. Lack of appetite is also a symptom of this disease.

Metronidazole is the drug used to treat Hexamitiasis.

Bent Spine(Scoliosis)

Scoliosis, or the abnormal curvature of the spine, is a condition that affects humans and fish alike. There are a few reasons why this might happen, including the way a fish is raised or its own genetics. This isn't a good thing for your fish to have since they won't be able to swim freely and can cause numerous issues with the growth of your fish.

The best way to deal with a fish that has scoliosis is to simply observe it. If the curvature of the spine isn't severe, then there's no need to do anything.

Poecilia Reticulata


What Do Poecilia Reticulata Eat? 

Poecilia reticulata are omnivorous and will eat a variety of foods, including live food, frozen food, pellets, and flakes. In the wild, their diet consists mostly of insects and small crustaceans. In captivity, they should be offered a variety of foods to ensure that they are getting all the nutrients they need.

What is the Maximum Size of a Poecilia Reticulata? 

The maximum size of a Poecilia reticulata male is about 3 inches (7.5 cm) whereas the maximum size of a female is about 5.5cm.

How Do You Breed Poecilia Reticulata?

Keep male and female guppies together in a well-maintained tank to breed guppies. Male guppies are generally brighter and more colorful than female guppies, and they're usually smaller. Guppies breed quickly on their own, so there's no need to do anything special to get them to breed. The female guppy will give birth to live young (called fry), and the fry will be able to fend for themselves.

What Kind of Behavior Does the Guppy Have?

Not only are they active and lively, but also very peaceful. They will ignore the other inhabitants of the aquarium, making them ideal for those who want a community tank. Guppies are also known to be good jumpers, so be sure to have a tight-fitting lid on your aquarium.

Do Guppies Get Along With Other Fish?

Yes, guppies generally get along with other fish. They are a peaceful species and will not bother other fish in the tank. As long as the other fish are not too large (which could eat the guppy), they should be fine together.

How Often Should I Feed My Guppy? 

You should feed your guppy 3-4 times a day, offering only as much food as they can eat in two minutes. Guppies are known to be voracious eaters, so it's important not to overfeed them.

What is the Life Span of a Guppy?

The average life span of a guppy is 2-3 years, but some have been known to live more than that.

Which Aquarium is Suitable for Guppy?

The Guppy fish is very versatile and can adapt to most aquariums, but they prefer a more natural habitat that replicates their natural habitat in the Amazon. This comforts and provides a variety of hiding places for the females, as well as secure locations for the youngsters. Guppies, on the other hand, need plenty of swimming room. Investing in tank plants like the Pistia is a great way to shade the aquarium and bring it closer to nature for your fish. In addition, the Guppies do not enjoy powerful currents. So choose an aquarium filter that does not produce too much movement in the water.

Is My Guppy Fish Pregnant? 

If your female guppy fish is getting larger, has a gravid spot, and is staying close to the surface of the water, she may be pregnant. Females are generally larger, less colorful, and have a fan-shaped anal fin behind their bellies. Approximately every 30 days, they give birth and will predate on their own young unless you provide lots of hiding spots for the fry. If you want to produce a lot of children, offer them more food and do partial water changes more frequently to maintain the water quality high.

How Do I Know If My Guppy Is Sick? 

If you notice any of the following signs, your guppy might be sick:

  • Loss of appetite
  • Lethargy
  • Floating upside down
  • Clamped fins
  • White spots on the body or fins
  • Rapid breathing

If you notice any of these signs, it's important to take action right away. First, check the water quality in your tank. Ammonia and nitrite levels should be 0, and nitrate levels should be less than 20 ppm. If the water quality is good, then you may need to treat your fish for a specific disease.

Why Are My Guppy Fish Dying? 

The reality is that guppies sold in pet stores tend to be weaker. The reason they get those amazing colors is due to inbreeding, which also unfortunately makes them more susceptible to disease because they're mass-produced and kept in very crowded conditions. Because they're carried all over the world to wholesalers, distributors, and then your local pet shop, they might acquire sicknesses at each stage of the journey. So by the time you receive your guppies, they may need a lot of care and attention. Make sure to have clean water, a nutritious diet, and the proper medications on hand to treat illnesses and infections. Other reasons for guppy fish death include:

  • Old age
  • Lack of food
  • Poor water quality
  • Overcrowding
  • Disease/infection
  • Accidents ( getting sucked into the filter, for example)

There are a few things you can do to help prevent your guppy fish from dying.

  • Start with healthy fish. If possible, buy your guppies from a breeder or someone who takes good care of their fish.
  • Quarantine new fish. When you bring new guppies home, keep them in a separate tank for at least two weeks. This will help prevent them from spreading any diseases to your existing fish.
  • Keep your tank clean. Regular water changes and vacuuming the gravel will help remove waste and toxins from the water.
  • Feed them a nutritious diet. Guppies need high-quality food that contains all the nutrients they need to stay healthy. There are many good brands of guppy food available, so talk to your local fish store or breeder to find one that would be best for your fish.
  • Provide them with plenty of hiding places. Guppies like to have plenty of places to hide, so be sure to include some plants and other decorations in your tank.
  • Monitor the water quality. Be sure to test the water regularly to make sure the pH, ammonia, and nitrite levels are all within the proper range.
  • Avoid overcrowding. Overcrowding can lead to stress and disease, so be sure to not put too many fish in your tank.
  • Watch for signs of illness and treat accordingly. Guppies are prone to a few different diseases, so it's important to be on the lookout for any signs of illness. If you see any sign of illness, be sure to take your guppy to the vet right away.

Final Thoughts

Poecilia reticulata, also known as Guppy fish, is a popular freshwater aquarium fish that is easy to care for and breed. They are native to South America but have been introduced to many other parts of the world. Guppies are livebearers, which means they give birth to live young instead of laying eggs.

Guppies are an excellent choice of fish for beginner and experienced aquarium keepers alike because they are beautiful, small, and breed quickly. They are relatively easy to care for as long as you provide them with a clean tank, plenty of hiding places, and a nutritious diet. Be sure to monitor the water quality and watch for signs of illness. They are omnivores that accept a wide variety of foods. The best food for guppy fish is high-quality flakes or pellets that contain all the nutrients they need to stay healthy.
