White Guppy Fish – Everything You Need To Know

Guppies are popular among fish enthusiasts for their beautiful tail fins and color patterns. As livebearers, they directly give birth to fry rather than laying eggs. Guppies are also known to be great "starter fish" for those new to the hobby. They generally require less care than other species of fish and come in various colors and shapes. One among the wide varieties of guppies is the White Guppy Fish.

White guppies are tiny fish with elongated bodies. Their short sizes make them appear quite lovely. The white guppies' black eyes set them apart from albino fish, and their milky white base color has no pink or red tinge. The objective is to produce a line that lacks any additional colors or designs.

In this article, we will discuss everything about White guppies including their appearance, diet, care, breeding, and much more. Let's get started!

White Guppy Care

Originating from South America, the white guppy was initially found in Mountain Streams and brackish rivers. Wild populations of Guppies can now be found around the world for example Venezuela, Trinidad, Barbados, Singapore, and the USA. Guppies have also been introduced to many other countries as an easy, cheap, and attractive addition to home aquariums. The Guppy is one of the most popular freshwater tropical fish in the world and comes in a huge variety of colors and fin shapes.

White Guppies are very easy to care for and make great beginner fish. They are tolerant of a wide range of water conditions and will thrive in most freshwater aquariums. A minimum tank size of 5 gallons is sufficient for a group of White Guppies. They are peaceful fish and can be kept with other peaceful community fish such as Mollies, Platies, Swordtails, Endler's Livebearers, Girardinus species, and Heterandria Formosa.

White Guppies are Omnivores and will accept a wide variety of foods. A good quality flake food or pellet should form the basis of their diet but they will also enjoy live, frozen, and freeze-dried foods such as bloodworms, brine shrimp, and daphnia. Guppies should be fed 2-3 times a day.

White Guppies are livebearers and give birth to between 20 and 60 fry (baby fish) at a time. The gestation period is 26-31 days. White Guppy fry is very small and needs to be kept in a separate tank with hiding places and plenty of plants. The fry can be fed on commercial fry food or live/frozen foods such as brine shrimp and bloodworms.

White Guppy Size 

The white guppy grows to an average length of 2.5 inches (5-6 cm) for females and 2 inches (5 cm) for males.

The size of a guppy is determined by numerous elements, including diet, water quality, and genetics. The majority of guppies sold in pet stores are mutants that have been selectively bred to be far larger than their natural counterparts.

White Guppy Lifespan

The average lifespan of a white guppy is 2 years, although some can live much longer if properly cared for. The lifespan of a guppy is determined by various factors, including diet, water quality, and genetics.

When compared to other fish species such as goldfish and koi, however, which can live up to 20 years or more in captivity, guppies are relatively short-lived.

White Guppy Appearance

The white guppy, also known as Poecilia Reticulata, is a type of fish that's medium-sized and very distinctive looking. The majority of its body is covered in white scales. This includes the caudal fins, dorsal fin, and tail. They are bred to be genetically blonde and through selective breeding processes, the black gene trait is reduced to produce a cleaner-looking fish.

Unlike other color morphs, the white guppy does not have any spots or color patterns on its fins. The only thing that may be visible on their fins is a faint iridescent sheen. Their eyes are also black. These guppies, like any others, can be identified by their large fins that resemble a fan. The long-flowing fin is what sets them apart from other types of fish and makes them easily recognizable to humans.

No matter the lighting, these fish are beautiful and have the potential to be real scene-stealers in a tank full of other fish.

Gender differentiation 

Distinguishing a White guppy male from a female is a very simple task. The following physical traits will help you quickly identify the gender of your fish:-

  • White male guppies are generally shorter, and thinner in length, have bright colors, an attractive tail, and interesting markings and patterns. The anal fin is modified into a gonopodium.
  • White Female Guppies are longer, and bulkier, have pale colors, short fins, and a large abdomen with dark gravid spots, and eggs are also clearly visible in pregnant females.

White Guppy Behavior

Male guppies of the Ogon variety are solitary, peaceful fish that enjoy living in groups. They are not aggressive and will not harass other fish in the aquarium. Male guppies can become territorial with each other if there aren't enough females in the tank, but this is typically only an issue if there are no additional males.

These fish are very active and love to swim around. They're also not shy, so you'll often see them at the front of the tank greeting you when you come home.

Guppies are social animals that do best when living in groups. A bunch of guppies is called a shoal. Shoaling fish feel more protected in a group and will be less likely to hide away. They will also be more lively and have distinct personalities.

White Guppy Tank setup

It is not difficult to set up a tank for white guppies. They aren't picky about water quality, and they can survive in a wide range of pH levels. However, if you want them to live a long time and be healthy, you must maintain their tank correctly.

Tank Size 

Though white guppies can maneuver in a 10-gallon tank, they tend to prefer 20-gallon tanks when living with a community of fish.

There are many benefits in terms of their health and well-being when they have more space. They will also be less likely to nip at the fins of other fish in a larger tank because they won't feel so cramped.

Water Conditions

Although white guppies are not choosy about their water conditions and can exist in a variety of pH levels, they prefer alkaline water slightly with a pH level between 6.8 to 8.0.

These fish require a water temperature of between 72 and 80 degrees Fahrenheit. They can tolerate a wide range of temperatures, but they prefer colder water.

It's critical to keep the water clean and free of chemicals like ammonia and nitrates. These pollutants can accumulate rapidly in a small tank, causing damage or even killing your fish.


White guppies are not only messy eaters but also produce a lot of waste. So, you need to have a good filtration system that can handle the amount of waste they produce.

A hang-on-back filter or a canister filter is an excellent option for white guppy tanks. Both types of filters will provide adequate filtration for your tank.

If you have a small tank, a hang-on-back filter will be the better option because it's less expensive and easier to maintain. But if you have a larger tank, a canister filter will be more efficient at filtering the water.


White guppies do not need special lighting, and any aquarium light will do. However, if you want to see their colors more vividly, you should use full-spectrum lighting.

This type of lighting will also help bring out the colors of other fish in your tank.


The substrate is the material you use to line the bottom of your tank. There are many different types of substrates available, and you can choose whatever you like.

However, white guppies prefer a fine-grained substrate because they often sift through it looking for food.

Some good options for substrates include sand, gravel, and clay.


White guppies are not fussy about decorations and will do well with most aquarium decorations. However, they do prefer live plants over artificial ones. Live plants provide shelter and hiding places for your fish, which can make them feel more secure. They also help to oxygenate the water and remove toxins.

Some good plants for white guppy tanks include java moss, hornwort, and anacharis.

Other decorations include driftwood and rocks. These can provide hiding places and help to create a natural-looking environment for your fish. However, be sure to clean any decorations that you put in your tank before adding them to remove any toxins. And also make sure that the decorations are safe for your fish and won't damage their fins.

You can also add other decorations to your guppy tanks, such as statues, castles, or bridges. These decorations can help create a beautiful and unique aquarium. Be sure to leave some open swimming space in the tank; these fish are active swimmers and need room to move around.

White guppies do not need a special substrate, but they do prefer a sandy bottom. A layer of gravel or sand will provide them with a place to dig and will also help to keep the water clean. Fish keepers like to use substrates to help accentuate the colors of their fish. A white sand or gravel substrate will make the white color of your fish stand out. While a black substrate will make the white color of your fish pop. You can also use a mixture of colors to create a unique look for your tank.

White Guppy Tank Maintenence 

Although white guppies are low-maintenance, there are a few things you should do to ensure optimal health. The following is a list of maintenance tasks that should be performed on a weekly basis:

  • Perform a water change of 20-30%.
  • Clean the filter.
  • Remove any algae from the glass.
  • Check the temperature and adjust as needed.
  • Test the water quality and make adjustments as needed.
  • The weekly maintenance will help to keep your guppy tank clean and free of toxins.
  • It's also important to perform regular maintenance on your filtration system. At least once a month, you should disassemble and clean your filter media. This will help to ensure that your filtration system is working properly and efficiently.

The following is a list of maintenance tasks that should be performed on a monthly basis:

  • Disassemble and clean the filter media.
  • Check the hoses and tubing for leaks.
  • Clean the pump.

Performing regular maintenance on your tank will help to keep your fish healthy and happy.

In addition to regular maintenance, it's important to keep an eye on your fish and their tank. Watch for signs of stress or illness, such as lethargy, listlessness, or excessive hiding. If you notice any of these signs, be sure to check the water quality and make adjustments as needed.

White Guppy Tankmates

white guppies are compatible with a wide range of tank mates. These fish are docile and get along well with other community fish.

Some good tankmate choices for white guppies include:

  • Neon Tetras
  • Glowlight Tetras
  • Corydoras Catfish
  • Platies
  • Mollies
  • Swordtails
  • Barbs
  • Danios

The following is a list of fish that are not compatible with white guppies:

  • Bettas
  • Gouramis
  • Angelfish
  • Cichlids

Aquarists can find various color morphs of guppies. Some aquarists keep a tank with only one species of guppy, while others prefer to mix colors and patterns to produce a stunning and uncommon aquarium.

When choosing tank mates for your white guppies, be sure to choose fish that are similar in size and temperament. It's also important to avoid fish that are known as fin nippers, as they may damage the fins of your guppies. Also, keep these fish species only with other fish varieties that require similar care. Observe your fish carefully to make sure they get along well together. If you see any aggression, remove the aggressor fish from the tank.

White Guppy Diet

White guppies are omnivores that will consume just about anything. These fish eat insects, crustaceans, and larvae in the wild. In captivity, they will eat flaked foods, pellets, and granules. You may also give them live, frozen, or freeze-dried meals as supplements to their diet.

  • Live foods: Live foods are high in minerals and vitamins, which help to enhance growth. It may aid in the natural color of your fish. It can be used as a treat or can be used to prepare your fish for breeding. However, make sure not to use live food all the time as it can contain parasites that may infect your fish.
  • Frozen foods: Feeding your fish frozen foods has several benefits. They're easy to find and convenient, they usually don't contain parasites as live foods can, and they help bring out natural colors. However, too much of a good thing is bad - only give them these as treats or use them to condition your fish for breeding purposes.
  • Pellets and Flakes: These are the most popular variety of fish food and may be found in any pet shop. They're high in nutrition and contain all of your fish's required vitamins and minerals. Choose a pellet or flake that is designed specifically for guppies based on the label.
  • Granules: These pellets are similar to others but smaller in size. They sink slowly, so they're good for fish that stay near the bottom of the tank. Make sure the granules you choose are small enough for your fish to eat comfortably.
  • Vegetables: You may also add fresh veggies to their diet as a supplement. Zucchini, carrots, peas, and spinach are some excellent fish foods. Make sure you cut them into tiny pieces so your guppy can consume them easily.
  • Algae wafers: Algae wafers are an excellent food for bottom-dwelling fish, such as white guppies. These wafers sink to the bottom of the tank and provide your fish with a nutritious meal. Moreover, they help to keep the tank clean by consuming algae.

There are many things to consider when choosing the right diet for your fish. The type of food, the frequency of feeding, and the portion size all play a role in keeping your fish healthy and happy.

  • The best way to determine how much to feed your fish is by looking at them. Overfeeding is one of the leading causes of poor water quality and can lead to health problems in your fish. If you see that your fish are getting fat, cut back on the amount of food you're giving them. It's better to underfeed than to overfeed.
  • It's also important to consider the type of food you're giving them. Some foods, such as live foods, can cause parasites if not fed in moderation. If you're going to feed your fish live foods, make sure to do your research and get them from a reputable source.
  • When it comes to feeding frequency, most experts recommend feeding your fish 2-3 times per day. This gives them enough food to eat without overfeeding them. If you're not sure how much to feed them, start with a small amount and increase it gradually until you find the right balance.

White Guppy Diseases

Although white guppies are quite resilient, they can still contract diseases if kept in unfortunate living conditions. Some of the most common sicknesses among these fish include:

  • Gill Flukes: Gill flukes are tiny parasites that infect your fish's gills and cause respiratory problems. Lethargy, hunger loss, and increased breathing rate are all signs of gill fluke infestation. If left untreated, gill flukes can be fatal. Raising the water's temperature to 86°F (30°C) for two weeks is the most effective approach to get rid of gill flukes.
  • Ich: The disease ICH or white spot is caused by Ichthyophthirius multifiliis. Cryptocaryon irritans cause saltwater ich, which is a type of white spot disease. Treatment of both parasites' lifecycles is difficult since they have a complicated life cycles. The parasite's feeding stage, when it appears as white spots on the fish's body, is very resistant to treatment. The only time you can treat the free-swimming stage of the parasite's life cycle is when the parasite is not visible. In order to get rid of the parasite entirely, you must therefore treat your fish during both stages. The most effective method is to raise the water temperature and add salt, which will kill the parasites in their free-swimming stage. Once that's done, use a commercial treatment to kill any remaining parasites in the latter feeding stage.
  • Columnaris: The purpose of this paper is to explore columnaris, a bacterial infection that usually appears on the skin or gills of fish. It tends to occur due to inadequate water quality. Some common symptoms are fraying fins, ulcers, and lethargy. If left unchecked, columnaris can kill your fish. The recommended method for treating columnaris is to use a commercial treatment product that is specifically designed for columnaris.
  • Velvet Disease: Amphiprioninae is the parasite that causes velvet disease. Lethargy, appetite loss, and a greater breathing rate are all symptoms. If left untreated, velvet disease may be deadly. Raising the temperature of the water to 86°F (30°C) for two weeks is the most effective way to get rid of parasites. You can also use a parasite treatment designed for aquariums.
  • Dropsy: Dropsy is an ailment that causes your fish to ooze fluid from its body. It is often brought on by unclean water or bacterial infection. Warning signs include lethargy, loss of appetite, and a rapid uptick in respiratory rate. If bacteria are the issue, then the infection can develop too quickly for the fish to be cured. In order to avoid contaminating healthy fish, those that are sick should be kept in a different tank away from others. Doing a 50 percent water change in the original aquarium as well as keeping an eye on any early signs and symptoms of dropsy for the remaining healthy fish is important.


To ensure the health of your fish, check up on them frequently for any signs that they may be sick. Some telltale symptoms of the disease are:

  • Lethargy
  • Loss of appetite
  • Increased respiration rate
  • White spots on the body
  • Ulcers
  • Fraying fins

If you notice any of these symptoms, you should isolate the affected fish in a hospital tank and consult a veterinarian.


It's always preferable to prevent disease in your fish than to try to cure it, so take precautions to keep sickness at bay. The following are some of the most effective strategies:

  • Quarantine new fish: Aquarium fish owners should always quarantine new fish for a minimum of two weeks. This timeline allows you to watch the new arrivals for any diseases or illnesses, and treat them before they have a chance to spread to your other fish.
  • Change your water regularly: It's critical to change your aquarium water on a regular basis to keep it clean and toxin-free. Every week, change approximately 20-25% of the water.
  • Use a filter: Filters are necessary for keeping your aquarium water clear. It will aid in the removal of pollutants and waste from the water, resulting in a healthier aquatic habitat for your fish.
  • Avoid overcrowding: If you overcrowd your fish tank, it can cause stress and water quality problems, which makes your fish more vulnerable to disease. Make sure you have enough space for all of your fish, and that they have plenty of room to swim.
  • Monitor your water quality: Be sure to frequently test your aquarium water quality with a straightforward kit. If the results aren't what they should be, take action immediately.
  • Feed your fish a healthy diet: A healthy diet is important for the overall health of your fish. Be sure to feed them a variety of foods that are rich in nutrients.
  • Provide a clean environment: A clean aquarium is a happy aquarium. Be sure to remove any debris or waste from the tank on a regular basis.


Treating disease in fish can be difficult. It's important to consult a veterinarian if you think your fish is sick. They will be able to diagnose the problem and recommend the best course of treatment.

Some common treatments for fish disease include:

  • Antibiotics: Antibiotics are the most common form of treatment for bacterial diseases. They can be administewhite through the water or by feeding your fish medicated food.
  • Aquarium salt: Aquarium salt can be used to treat many different diseases. It is most effective against parasites and fungal infections.
  • Raising the temperature: Raising the temperature of the water can kill parasites and bacteria. It is most effective against velvet disease and ich.
  • Commercial treatment: Commercial treatments are available for many different diseases. They are typically the most effective form of treatment. If you notice any of these symptoms, you should isolate the affected fish in a hospital tank and consult a veterinarian.

Treatment will vary depending on the specific disease. Always consult a veterinarian for the best course of treatment.

White Guppy Breeding

Water maintenance, regular filtering, and a natural-looking environment are all crucial for guppy breeding and raising to be successful. Even if left alone, guppies produce swiftly, so you should plan ahead for tank size and filtration requirements. It's always better to prepare for more children than expected, therefore make sure there is an adequate area in the event you have more babies than anticipated!

  • Maturity of the fish
    One of the reasons guppies are popular for breeding is that they have a rapid maturity rate. Guppies mate internally, and the fry (baby fish) are born fully formed and capable of taking care of themselves from birth. The parents don't help to raise their young, but this lack of parental involvement doesn't seem to adversely affect the fry. They grow quickly and reach maturity within a short time period.
  • Maturity of the fish

    One of the reasons guppies are popular for breeding is that they have a rapid maturity rate.

The parents don't help to raise their young, but this lack of parental involvement doesn't seem to adversely affect the fry. They grow quickly and reach maturity within a short time period.

    Guppies reach sexual maturity at around 4-5 months of age. At this point, they are fully grown and able to mate. However, it's best to wait until they are 6-8 months old before breeding them. This gives them time to grow and develop properly and results in healthier fry.
  • Spawning

    Guppies are livebearers, giving birth to live young. Guppy fry is born ready to take care of themselves and fully formed. After mating, female guppies can store the male's sperm in her body for several months, using it to fertilize her eggs multiple times without having to mate again.
  • Broods

    Female guppies can produce hundreds of fry at a time, with an average litter size of 5 to 20 fry. Some females, on the other hand, may have up to 100 fry at once! The number of fry in a litter is determined by the mother's size. Larger mothers usually produce more offspring per batch.

Selective Guppy Breeding

If you want to selectively breed guppies, first choose a few with qualities you'd like to improve so they can create true-breeding strains. Some helpful characteristics to look for include long fins, intriguing coloration, and patterns. It is essential to purchase a female from the same strain as the male in order to strengthen the line and save time. Although females don't express many traits visible in males, they still play a role in carrying genes necessary for expressing these traits.

While it is possible to find comparable fish from generation to generation, it is much more difficult than say, developing a new strain. Mutation is one way that new variants may appear, but in the world of breeding, almost anything is achievable.

  • Selecting the Breeding Pairs
    The best way to improve a guppy strain is by breeding the healthiest and strongest individuals. This may require some research on your part, but it will be worth it in the end when you have a tank full of beautiful, healthy fish.

    To get started, begin by selecting a male and female from the same line or strain that expresses the desired characteristics. If you're not sure which guppies to choose, ask the breeder or store owner for help. They will be able to point you in the right direction.
  • Determining and Separating Sexes
    Because single insemination may produce a succession of broods, it's best to split the sexes as quickly as possible so you can influence which males father the following generation of guppies. In some situations, the newborn fry may be able to reproduce in as little as three months. The distance between the anal fin and the pelvic fins is an easy method to determine whether or not your guppies are male or female. The female's anal fin is located far behind the pelvic fin, while the male's fin advances forward until it comes to a stop between these fins at maturity. It is simple to tell if a female is pregnant by noting her physical appearance. The female will grow considerably larger and acquire a gravid spot on her belly, which will become darker and more defined as delivery approaches. She will be able to produce another brood in one month's time after giving birth.
  • Inbreeding
    Although it may seem daunting, don't be afraid to inbreed your strain of guppies. A Danish scientist once did so for 24 years without adding any new blood and found that the end result was a stronger and healthier strain of guppy with no apparent damage caused by inbreeding! If you do find that your fish's quality is decreasing, you can always cross them with another strain.

    Keep an eye out for any males that are born with unusual traits that may be developed into new lines as new generations are produced.
  • Feeding the Fry
    We can help our newborn fry grow as big as possible by feeding them freshly hatched brine shrimp. We also need to make sure there are numerous plants (both rooted and floating) so that the fry may hide after eating. This method ensures that their body size increases, preventing them from being eaten by other fish if we aren't using a breeding tank.

    Guppies are omnivores that enjoy a diet that includes both animal and vegetable components. Vegetable flakes, ordinary flakes, live brine shrimp and live, frozen, and freeze-dried foods should all be included in a balanced menu. Fresh spinach or freshly chopped dark green lettuce will also be appreciated.

    Feed your guppies twice a day and remove any food that hasn't been eaten after five minutes. Keep in mind that guppies have small mouths, so avoid giving them coarse foods. Also, since guppies have a long gut, they will usually only eat small portions at once.
