Red Guppy Care

If you are looking for a beautiful and low-maintenance fish to add to your home aquarium, red guppies are a great option. Red guppies are peaceful fish that do well in community tanks with other peaceful species. They are known for their beautiful colors and long fins, but they are also easy to care for and relatively low-maintenance. However, there are a few things you should know about Red guppy care in order to ensure that your fish are happy and healthy.

When caring for Red guppies, water quality is one of the key things to remember. These fish originate from tropical areas including Asia, Central America, and Brazil. In their natural habitat, they normally stay in slow-moving waters like ponds or swampy streams.

Aquariums that resemble their homeland as much as possible will create the best environment for them. For example, your tank should have a sandy substrate with lots of plants for the fish to hide among. Because these fish are delicate, it's crucial to have clean water with low ammonia levels.

Test the tank regularly and do partial water changes often to maintain a healthy environment for your fish. Furthermore, overfeeding can create dirty conditions, so be careful not to overdo it when feeding time comes around.

Another important aspect of Red guppy care is what you feed them. In the wild, these fish are omnivores who eat live food, frozen food, and flake food. In captivity, you may offer your fish a variety of commercially available foods. It's also critical to ensure that they have enough protein in their diet.

Dive deeper into Red guppy care, from tips on tank setup to what they eat and which fish get along best with them.

Red Guppy Size

The average length of a Red guppy is approximately 2.5 inches, although they can reach up to 3 inches long. Pay attention to your guppies' diet and living conditions if you want them to be as big and healthy as possible. Smaller-than-average guppies are usually the result of inbreeding or poor nutrition, so make sure their food and water quality is good if they seem tiny. Your guppies may develop their full potential size with the right setting and care.

Red Guppy Lifespan 

Your Red guppy can live up to 2 years with proper care, which includes a healthy diet and a stressed-free environment. The lifespan of your fish also depends on the quality of water in its tank. To help your fish live a long life, make sure their living quarters are clean and that they have enough food.

Choose a guppy pair to breed. The male should have large, colorful fins, and the female should be plump with a gravid spot. It's preferable to choose a young pair of guppies because they're more likely to produce healthy offspring. It is beneficial to choose three or four adolescent pairs to increase the possibility of reproduction.

Red Guppy Appearance

Red guppies, a variety of the Poecilia reticulata species, have distinctive red coloration and long-flowing fins.

The red guppy has two hues of pigments, carotenoid red and pteridine red. Carotenoid red comes from meals, as well as having health advantages. Female guppies are attracted to crimson stains while seeking a mate. The pteridine red is a reddish brown, and it is because of genetics.

Like any other guppy, the red guppy has a torpedo-shaped body. They have a single dorsal fin and an anal fin that is bigger in size compared to the dorsal. The fins are what give this fish extra beauty, and they can be of different colors and shapes.

Red Guppy Variations 

But did you know that there are actually several types of red guppies? The red guppies are classified into different variants by their unique body color and structure, including:

Full red: The common name "red fish" was given to this species because of the bright red color of its body. It has no single origin. These fish are a mix of various guppy strains that have been combined to form a whole fish.

Blond half black full red: Blond fish that are half black and full red have pure red fins without any black. The female of the blond, half black, and full red species have tails that are either red, blue, or green.

Albino full red: The Albino full red is a variation of this fish that eliminates the black color. The most common types of albino full red are albino full red swallow.

Marlbaro guppy: The full red and the complete red genes give a black ground color, making Marlbaro guppies attractive. These fish have a base color of black with shades of red, blue, or green on their bodies.

Albino glass belly red spear tail: The crimson red belly of the albino glass spear-tailed fish originates in China and is made up of albino genes.

Mosaic red fantail: The Mosaic red fantail is a type of guppy distinguished by its tail fin, which is shaped like a fan. This type of tail is characterized by its broad vertical size, short length, and rounded edge.

Big dorsal red tail: The Blond big dorsal red tail is a variant of the red guppy. It is characterized by its broad and tall dorsal fin that is red in color.

Gender Diferentiation

  • The easiest way to differentiate between the sexes is by looking at their tails. The male's tail is narrower than the female's, and its fins are much longer.
  • Females have a spot near their vent called a gravid spot, which turns dark when they are full of eggs.
  • Males have bright colors and patterns on their bodies that help them attract mates, while females are usually duller in color.
  • Females are larger than males and can grow to be up to 2.5 inches long, while males only grow to be about 2 inches long.

Red Guppy Behavior

Red guppies are active fish that enjoy swimming around the tank. They prefer to live in groups, so it's best to keep them in tanks with at least 5 other fish. They are not known to be aggressive toward other fish, but the males can be aggressive toward each other. If you have a male and female Red guppy, they will likely get along well.

They are not known to be fin nippers, but they may nibble on the fins of other fish if they are bored or hungry.

Red guppies are known to be good jumpers, so it's important to have a tight-fitting lid on your tank.

Red Guppy Tank Setup

Though Red guppies are not fussy eaters and can do well in different water conditions, they still need a clean tank to stay healthy - just like any other fish. So if you are a novice fish keeper, it's best to start with a smaller tank and work your way up.

Here are some tips for setting up a Red guppy tank:

Tank Size 

A minimum of 5 gallons is necessary for Red guppies, however, more than a handful will require a larger tank. A larger tank has plenty of advantages like space for the fish to move around and little water quality issues.

Now, If you want your aquarium to have various kinds of fish, remember their size and needs while picking a tank size.

Water Conditions 

Although the red guppy can survive in a wide range of conditions, it is important to maintain them at an appropriate level in order for them to fully develop. The temperature at which red guppies thrive is between 72-80 degrees Fahrenheit. If at all feasible, try to avoid sudden temperature variations since they are stressful for fish.

To ensure the best environment for your Full Red Guppies, maintain a water salinity of 6.0 to 8.0 and hardness at KH 8-12. Adhering to these parameters will allow your fish to thrive and show their beautiful colors.

Ammonia, Nitrites, and Nitrates should all be at 0 ppm. If any of these levels rise, it can harm or even kill your fish. To maintain 0 ppm for all 3, do a 30-50% water change every week and vacuum the gravel to remove debris that can rot and release these toxins.


Your filter should be able to turn over the entire volume of your tank at least 3 times per hour. A canister or hang-on back filter is best for this.

For a 5-gallon tank, a filter that can turn over 30-60 gallons per hour is necessary.

If you have a larger tank, you'll need a filter that can turn over the entire volume of your tank at least 3 times per hour.


It's not essential to provide special decorations for red guppies, although if you want to make your aquarium more appealing, there are several choices. Below are some recommendations:

Plants: Red guppies do not require live plants, but they do benefit from them. Plants aid in the maintenance of clean water and offer hiding places for fish. Live plants also enhance the oxygen level in the water. The following are some excellent plant choices for Red guppy tanks:

  • Java moss
  • Hornwort
  • Anacharis
  • Water sprite
  • Ludwigia

If you're finding it difficult to locate these plants in your area, don't worry – artificial plants are a great alternative. Be sure to select fish-safe plants that are made from non-toxic materials, and give them a good wash before adding them to the tank.

Rocks and Driftwood: These fishes like to hide when they are feeling stressed, so having some driftwood or rocks in your aquarium will give them a place to hide. Also adding this driftwood and stones to your aquarium might give it a more natural appearance. 

Make sure the pieces you pick are suitable for aquariums and won't affect the water quality. Touch it and make sure there aren't any sharp or jagged edges that could harm your fish. Before adding it to your tank, clean it thoroughly.

Substrate: Although red guppies don't need a special type of substrate, they do need some sort of foundation to keep their plants in place. A gravel base works well for these fish. Just be sure to pick rocks that are small enough so the guppy won't accidentally swallow them. As long as you maintain a sterile environment and refrain from placing anything harmful in the tank with your guppy, they should thrive!

If you want live plants in your aquarium, you need to add a nutrient-dense substrate. A good choice for live plants is an aquarium soil substrate.

Lighting: Red guppies don't require any special lighting, but if you want to bring out their colors, you can use full-spectrum LEDs. These will also help your live plants to grow.

Red Guppy Tank Mates 

The Red guppy is a peaceful fish, so it can be kept with many other types of fish. Some good choices for tank mates include:

  • Neon tetras
  • Guppies
  • Platies
  • Swordtails
  • Mollies
  • Danios
  • Barbs
  • Corydoras catfish

Do not keep Red guppies with fish that are known to be aggressive or nippy. These fish will stress the Red guppies and may even kill them. In addition, avoid mixing red guppies with the following tankmates:

  • Betta fish
  • Goldfish
  • Sharks
  • Cichlids

Any fish that is too large for the red guppy to eat should also be avoided. These fish may view the guppy as prey and attempt to eat them. When choosing tank mates for your red guppy, be sure to select fish that have similar care requirements. This will make it easier to maintain proper water conditions for all of your fish.

Tank Maintenance 

Proper tank maintenance is essential for the health and well-being of your red guppy. Be sure to do the following:

  • Perform regular water changes: At least once a week, you should remove 10-15% of the water from your tank and replace it with fresh, treated water. This will help to keep the water clean and free of toxins.
  • Vacuum the gravel: Every other week, vacuum the gravel in your tank to remove any debris that has accumulated. This will also help to keep the water quality high.
  • Clean the filter: Be sure to clean your filter regularly. This will help to remove any toxins or waste that has accumulated in the filter media.
  • Trim the plants: If you have plants in your tank, you may need to trim them back from time to time. This will help to keep the plants healthy and prevent them from taking over the tank.

 While performing tank maintenance, please keep the following things in mind:

  • Never remove all of the water from your tank. This will cause your fish to go into shock and may even kill them.
  • Be sure to use a gravel vacuum that is designed for aquariums. These vacuums are gentle and won't damage your fish or plants.
  • When cleaning your filter, be sure to rinse the filter media in old tank water. This will help to remove any toxins that may be present in the water.
  • While changing the water, use a water conditioner to remove any toxins that may be present in the tap water.

Red Guppy Diet 

Red guppies are omnivores that will consume a wide range of fish foods. flakes, pellets, frozen, and live food is all acceptable.

Here are some good food choices for Red guppies:

Flakes or pellets: A red guppy's diet should consist of high-quality flakes or pellets as they are easy to digest and contain all the nutrients a guppy needs. Be wary of foods with lots of fillers or artificial colors as these can harm your fish.

Live food: By adding live food to your Red guppy's diet, you are increasing the nutrient value they are receiving. Live food often contains more nutrients than pellets or flakes and can help keep your fish healthy overall. Some good examples of live foods include brine shrimp, daphnia, blackworms, etc.

Frozen food: Live food is more expensive to maintain, and frozen food is a viable substitute. It's more convenient and simpler to store than live food. Before feeding your fish, ensure that the meal has been thawed out properly.

Vegetables: Red guppies also enjoy vegetables. Blanched spinach, zucchini, and peas are all good options. To ensure that uneaten crops do not decay and pollute the water, remove any remaining veggies from the tank.

What Not To Feed 

There are some things that you should not feed your Red guppy as they can be harmful or even fatal. Some of these include:

  • Junk food: Human junk food, such as chips or candy, is not good for fish and should be avoided.
  • Raw meat: Raw meat can contain bacteria that can be harmful to your fish. It's best to avoid feeding them raw meat altogether. This does not include live food, which is safe for them to eat once in a while.
  • Expired food: Never feed your fish expired food as it can be poisonous. Always check the expiration date before feeding your guppies.

Feeding Tips

Here are a few tips to help you with feeding your Red guppies:

  • Feed them twice a day: It's best to feed your guppies twice daily, once in the morning and once at night. This will help to ensure that they are getting enough food and nutrients.
  • Don't overfeed them: Overfeeding your fish can cause problems such as bloating and swim bladder disease. Only give them as much food as they can eat in a few minutes.
  • Have a varied diet: A varied diet is important for your fish to stay healthy. Be sure to offer them different types of food so that they are getting all the nutrients they need.
  • Remove any uneaten food: Any uneaten food should be removed from the tank as it can decay and pollute the water.

Red Guppy Diseases 

Although red guppies are tough, there are some diseases from which they cannot escape.

These include:


The fish's skin begins to develop tiny white spots, which is known as ich. It's caused by an ectoparasite (ciliate protozoan Ichthyophthirius multifiliis), making it extremely simple to detect. The fish begin rubbing their skin against rocks, plant leaves, or other objects in the aquarium. They can also lose interest in food. You'll notice little white dots on the fish's skin and fins. To cure ich, you'll need to raise the water temperature and perform a partial water change.

Follow the following:

Check the temperature of the water on a daily basis to ensure that it does not exceed 80 degrees Fahrenheit. Follow the manufacturer's instructions for adding medication. Add aquarium salt, according to the manufacturer's recommendations, at a rate of 1 teaspoon per gallon. Allow 4-7 days for this phase to run its course before checking on it again. Gradually return the water temperature back to normal over a period of several days or weeks.

Once the ich has been eliminated, it's important to take measures to prevent it from happening again. This includes quarantining new fish before adding them to the tank and keeping the aquarium clean.


The most common form of anemone blenny disease is velvet disease. It's also known as ich, but it's considerably less common to find in aquariums kept by amateurs. A fish with velvet might have tiny golden-colored dots all over its body, making it appear like grains of dust. If you don't take precautions, this condition may quickly spread to every one of your other fish.

Fish keepers often discover problems with a fish's skin too late because the early stages are difficult to detect. A fish's skin is velvet and small dots make it hard to see changes. When the skin starts peeling and there is blood, then owners know something is wrong.

To cure velvet:

Velvets can be treated with copper medication. To most effectively treat your aquarium, turn off the lights until the disease is gone. Once your fish are symptom-free, perform 70-90 percent water changes every other day for at least two weeks.

Fin Rot 

Guppies that have rotting fins and tails suffer from a bacterial infection, which causes their fins and tail to appear welded together. This can also be caused by a fungus that develops on nipped fins. In addition, poor water quality and ammonia burns are two additional factors that cause decaying tails.

It is crucial to identify the cause of rotting fins because treatment for bacterial infection or fungus differs. If there is no damage to the fins and tail but they have started rotting, bacteria are most likely the culprit.

If your fish has fin rot, you should isolate it and give it antibiotics. However, if the cause of the fin tail rot is a fungus, then treat it with special medication – always following instructions on said packaging. In order to avoid "ammonia burns", be sure to provide high-quality water for your fish.


Guppies are the most common hosts for the protozoan parasite, which can infect them. Although other fish may become sick as well, guppies are by far the most prevalent host for this little creature. The parasite latches onto the fish's skin and works its way into the fish's body via its muscles until it reaches circulation.

When water quality is bad, this worm generally develops in shoddy tanks.

If your fish has protozoan, heat the water in their tank to keep the temperature stable. This can be treated with Malachite Green or Formalin at early stages, and copper medications like Seachem Cupramine should be used for more severe cases. After treatment, change 50-70% of the water.

Water quality is important for the prevention of all these diseases. Add an ammonia remover to your guppy tank and change 20-30% of the water every week. This will help to keep the levels of ammonia and nitrites low, which will create a healthier environment for your fish.


This infection, which appears to be fungal but is actually caused by bacteria, typically grows as a large white sludge on the fish's mouth or midsection. The colony of bacteria slowly paralyzes their muscle and patients have difficulty swimming and lose their appetite.

Guppies are highly susceptible to the disease and can become infected if they come into direct contact with an affected guppy. The illness is highly transmissible and predominantly affects female guppies, although male guppies can also be ill. If the infection isn't treated, it has the potential to eradicate the tank's entire fish population.

The best way to fight Columnaris and mouth fungus is to immediately begin the treatment process once any symptoms become apparent. Two popular drugs used for this purpose are Maracyn and Formalin. In addition, increasing the salt content in your aquarium can also be helpful: do a 50% water change and add one teaspoon of salt per gallon every day for three days after the initial water change.

Only remove the salt from your fish tank once it has completely healed. In addition, a 30-minute potassium permanganate (KMnO4) bath can cure Columnaris; however, use this treatment with caution. Potassium permanganate is a powerful oxidizing agent and exceeding 10mg/l in the bath risks burning your fish.


Lethargy is the most frequent sign of unhealthy water conditions. If your guppy has no energy, and isn't swimming or eating, poor water quality is likely the cause.

Other symptoms include:

  • Gasping for air at the surface of the water
  • Clamped fins (when the fish's fins are held close to their body)
  • Slimy or discolored skin
  • White spots
  • Fungus on the skin or fins (Saprolegnia)
  • Fin and tail rot
  • Red patches on the skin
  • Bulging eyes
  • neurological disorders such as swimming in circles or upside down

If you notice any of these symptoms, it's important to take action immediately in order to save your fish's life.


The following are some tips that will help you prevent your guppy from getting sick:

  • Keep the water in their tank clean and free of ammonia and nitrates.
  • Do a partial water change every week and clean the gravel at the bottom of their tank.
  • Don't overfeed your fish – only give them as much food as they can eat in a few minutes.
  • Don't put fish of different sizes together in the same tank.
  • Avoid putting stressors in their environments, such as bright lights or loud noises.
  • Keep their tank at a stable temperature between 72-82 degrees Fahrenheit.

Red Guppy Breeding 

It's critical to understand that guppies breed quickly and can fill a tank rapidly if they are not controlled. Guppies are livebearers, which means they give birth to living youngsters instead of laying eggs.

These steps will show you how to breed guppies:

Choose a guppy pair to breed. The male should have large, colorful fins, and the female should be plump with a gravid spot. It's preferable to choose a young pair of guppies because they're more likely to produce healthy offspring. It is beneficial to choose three or four adolescent pairs to increase the possibility of reproduction.

Setting up a breeding tank is easy and only requires a few materials. First, you'll need a 10-gallon tank or larger. The female guppy will also need plenty of hiding places; you can use live or plastic plants for this purpose. In addition, be sure to have a fine-mesh net on hand to catch the fry (baby fish) when they're born. Finally, set the temperature of the breeding tank between 75-80 degrees Fahrenheit prior to adding any fish.

After the breeding tank is prepared, place the guppies inside and let them acclimate to their new surroundings for an hour before giving them free rein in the tank.

After the female guppy gives birth, wait for the fry to be born. She will give birth to anywhere from 20-60 fry at a time. They are very small and vulnerable, so have a net ready to catch them as soon as they're born. Once all of the fry are out, remove them from the breeding tank and place them in their own tank.

Feed the fry. The fry will need to be fed several times a day, and it is recommended that you do so for at least four hours. You may feed them with live baby brine shrimp or specialized fry food. You can start feeding them adult guppy food when the fish are about two weeks old

Keep an eye on the fry tank. To avoid sickness, keep the fry tank clean. Every week, replace the water in the tank and remove any uneaten feedings. Once your trout is four weeks old, it may be transplanted to a larger aquarium.
