Leopard guppy – Best Aquarium Fish

Guppies are one of the most popular fish for aquariums. They are easy to care for and can live in a variety of conditions. Guppies come in many colors and patterns, making them a favorite among fish enthusiasts. Leopard guppy is one such color variation that is loved by many.

The Leopard Guppy is one of the numerous various species of Poecilia reticulata guppies that have been developed over many years through careful, selective breeding. The male Luminous Leopard Guppy has an unusual range of iridescent body coloration guppies. The Luminous Leopard Guppy tail is black with leopard-type markings. It also has beautiful yellow and orange hues, accented by dark spots that resemble a leopard. This guppy is sought-after because of its attractive body coloration.

In this article, we will discuss everything you need to know about leopard guppies, including their care, diet, tank mates, and more.

Leopard Guppies Size

The Leopard Guppy is a tiny fish that grows to be only 2.5 centimeters long. These fish species need appropriate care in order to achieve their maximum potential size. The quality of the guppy's diet and whether or not it has access to hiding places in its tank can affect its size.

Leopard Guppies Lifespan

The average lifespan of a Leopard guppy is two years, although it is believed that some specimens may live up to three years under optimal care. The majority of fish, on the other hand, will not exceed two years in length.

The type of diet, tankmates, and stress level of a guppy have an impact on their longevity.

Leopard Guppies Appearance

Leopard Guppies are small, brightly colored fish. The males of this species tend to be more brightly colored than the females.

The bodies of these fish are torpedo-shaped and their tails are long and flowing. Leopard Guppies have a variety of color patterns, but the most common colors are orange, yellow, and black.

These fish also have spots on their bodies that resemble those of a leopard. Some Leopard Guppies also have stripes running along their sides. However, the patterns and colors of these fish can vary widely.

Like all guppies, Leopard Guppies have a set of pelvic fins that are located just behind their gills. These fins help the fish maneuver in the water and to brake when they are swimming.

Leopard Guppies also have a dorsal fin that is located on their backs. This fin helps the fish to balance themselves in the water and to stay afloat. The anal fin of these fish is located on its underside, just behind the pelvic fins. This fin helps the fish to stay stable in the water and to move forwards.

Leopard Guppies Behavior

These beautiful fish species are popular because of their pleasant natures and amiable dispositions, making them excellent companion fish for other fish. They are relatively docile and get along well with other tank mates.

Leopard guppies are also known to be quite active and playful, often swimming near the surface of the water. They enjoy exploring their tanks and will often hide in plants or other decorations.

Sometimes, however, Leopard guppies may exhibit aggression towards one another, particularly during mating season. This is normal behavior and usually nothing to worry about as long as the fish are otherwise healthy.

Leopard Guppies Tank Setup

Setting up a Leopard guppy aquarium is not difficult, but there are a few things to bear in mind, especially if you are new to fish keeping.

Tank Size

Leopard guppies are very similar to regular guppies, but they have some unique needs. Each Leopard guppy needs approximately 5 gallons of water and can grow to be about 2 inches large. They also appear to be sociable creatures that like living in groups, so it's probably best if you don't keep just one Leopard guppy. If you have four Leopard guppies, for example, you might want a 20-gallon tank or larger.

Water Condition

Leopard guppies are tropical fish that generally prefer warmer waters of 77 to 80 degrees Fahrenheit (25 to 27 Celsius). However, they're very adaptable fish as well, having learned from living in their natural habitats where weather conditions can change frequently.

When it comes to temperature, they can survive in temperatures as low as 63°F (17°C), but when breeding, you must maintain higher levels. To do so, you may need a heater. The ph range should be from 7.0 to 8; however, it can also be at a neutral point. Water hardness should be at a level of 8-12 dGH.


In order to maintain a healthy fish population, you need filtered and clean water. This will help your fish stay disease-free while promoting their overall health. There are several types of filters available for aquariums; with canister filters, power filters, and hang-on-back filters being the most common. Do some research to see which filter would provide the best results for your tank specifically. Canister filters are a bit more expensive but they're very efficient and will last a long time. Power filters are less costly but need to be replaced more often. Hang-on-back filters are an excellent middle ground - they're not as expensive as canister filters but they last longer than power filters.

You should also consider getting a filter that has a UV sterilizer to help keep the water clean and free of bacteria.

Tank Decor

You have a wide variety of choices when it comes to decorating your Leopard guppy tank. These fish are not fussy and will thrive in most setups.

Leopard guppies are eye-catching fish that enjoy swimming near the top of your aquarium, so be sure to give them enough space to swim and explore.

Some people like to add live plants to their tanks, which can provide hiding places for the fish and help to keep the water clean. If you decide to add live plants, be sure to research which ones are best for freshwater aquariums. Some plants require special care and might not do well in your tank.

Other popular tank decorations include rocks, driftwood, and artificial plants. You can also add a gravel substrate to the bottom of the tank.

When choosing decorations, be sure to avoid anything that is sharp or could potentially hurt the fish.

Leopard guppies do not need special lighting, but you will need to provide some light for live plants (if you decide to add them to your tank). A fluorescent tube light or LED light will work well. Be sure to get a light that is specifically designed for aquariums so that it will not produce too much heat.

Tank Maintenance

Maintaining a clean and healthy aquarium is crucial for the well-being of your fish. There are several things you need to do on a regular basis to keep your tank in good condition, such as:

  • Cleaning the tank - You'll need to remove all the dirt and debris from the tank on a regular basis. The best way to do this is with a gravel vacuum.
  • Cleaning the filter - The filter helps to keep the water clean, so it's important to clean it on a regular basis. Depending on the type of filter you have, you may need to replace it every few months.
  • Changing the water - You'll need to change at least 10% of the water in the tank every week. This helps to keep the water clean and prevents it from becoming stagnant.
  • Monitoring the levels - You'll need to check the levels of ammonia, nitrites, and nitrates in the water on a regular basis. If they get too high, it can be harmful to your fish.
  • You should also perform a partial water change every month. This involves removing some of the water from the tank and replacing it with fresh, clean water.

Compatible Leopard Guppy Tank Mates

The peaceful Leopard guppy is a great tank mate for other fish with similar temperaments. Tank mates for Leopard guppies include:

  • Mollies
  • Platies
  • Swordtails
  • Endler's livebearers
  • Girardinus species
  • Heter

There are some tankmates that are not compatible with Leopard guppies such as:

  • Goldfish
  • Cichlids
  • Sharks
  • Bettas
  • Dwarf gouramis
  • Loaches
  • Pufferfish

If you are planning to add Leopard guppies to an existing tank, be sure to do your research and choose tankmates that will get along well with them. If you find that your Leopard guppies are not getting along with other fish in the tank, you may need to remove them and find a new home for them.

Leopard Guppies Diet


Leopard guppies are Omnivores, which means that they eat both plants and animals. In the wild, their diet consists of small insects, larvae, worms, and other tiny creatures. They will also consume algae and other plant matter. In the aquarium, you can feed your Leopard guppies a variety of food such as:

  • Fish flakes: You can find fish flakes at your local pet store or online. Be sure to get a high-quality brand that is specifically designed for freshwater fish.
  • Granules: Granules are similar to fish flakes but are a bit larger in size. They're a good option for Leopard guppies that are a bit larger. Granules are rich in nutrients and will help keep your fish healthy.
  • Live food: Live food is a great option for Leopard guppies. They love to chase and eat small live insects such as brine shrimp, daphnia, and bloodworms. You can find live food at your local pet store. However, it is not recommended to feed them live food all the time as it can lead to health problems.
  • Frozen food: Frozen food is a convenient option and is just as nutritious as live food. You can find frozen bloodworms, brine shrimp, and daphnia at your local pet store or online. Be sure to thaw the food before feeding it to your fish.
  • Vegetables: Vegetables are a good source of vitamins and minerals. You can feed your Leopard guppies blanched vegetables such as zucchini, cucumber, and spinach.

You need to feed your Leopard guppies 2-3 times a day. Give them only as much food as they can eat in 2 minutes.

Do not feed your fish in large quantities, as overfeeding can lead to health problems such as obesity and swim bladder disease.

Remove any uneaten food from the tank so that it does not pollute the water.

Make sure to provide your Leopard guppies with a varied diet so that they can get all the nutrients they need.

Live foods must not be fed to Leopard guppies on a regular basis as it can lead to health problems.

Leopard Guppies Diseases

Guppies are generally quite hardy fish and don't get sick often. However, there are a few diseases that they are susceptible to, so it's important to be aware of them.

Some common diseases that affect Leopard guppies include:

  • Ich: The most common problem in the fishkeeping hobby is white spot diseases, which are known as white spot ailments. If Ich is treated promptly, it is not deadly. Ich is caused by an ectoparasite (ciliate protozoan Ichthyophthirius multifiliis) and is easy to see. The fish begin to rub their skin against rocks, plant leaves, decorations, or the aquarium's sides. They may also lose their appetite. You will see tiny white spots on the skin and fins of your fish. It is not difficult to cure ich. There are a variety of medications available; however, you can also use aquarium salt.
  • Velvet: Velvet is a type of parasite that affects the skin and gills of fish. It is often confused with ich, but there are some key differences. Velvet is more difficult to see and usually only affects one side of the fish. The affected fish may also have trouble breathing and will often hide. If velvet is left untreated, it can be deadly. There are a variety of medications available to treat velvet, but the best way to prevent it is to quarantine new fish before adding them to your tank.
  • Fin rot: Fin rot is a bacterial infection that affects the fins of fish. It is often caused by poor water quality or injuries. The affected fish will often have ragged or torn fins. If fin rot is left untreated, it can be deadly. There are a variety of medications available to treat fin rot, but the best way to prevent it is to maintain good water quality and avoid injuries.
  • Protozoan: Protozoa is a tiny worm that primarily affects guppies. Other fish may be harmed as well, but guppies are the most frequent victims of this illness. The parasite attaches itself to the fish's skin and slowly crawls into its body via its muscle until it reaches circulation. Protozoal infections are generally seen in unheated tanks accompanied by poor water quality.
  • Columnaris: Although it appears to be a fungus, this illness is caused by bacteria. The colony of germs typically grows on the fish's mouth or middle third of the body as a large white splodge. Because the disease slowly paralyzes the muscle, sick fish have difficulty swimming. They also lose their appetite. The bacteria is highly contagious and mostly affects female guppies, but male guppies can also be infected if the illness is not treated. It can wipe out the whole fish colony in a tank.
  • Dropsy: Dropsy is an inflammatory disease of the liver or kidney that causes the abdomen to be filled with fluid it cannot expel. The fish becomes swollen, discolored, and occasionally deformed, with scales looking like pine cones protruding from its body. If a fish's belly becomes bloated, it could have trouble swimming. A bloating belly can also come from an excess of fluid in the colonic cavity. This might be due to water pollution, genetic disorder, or feeding habits. Overfeeding on blood worms or having long-term high stress could lead to dropsy.
  • Red Blood Paralysis: Also known as red body disease, this is a condition that affects fish in brackish and saltwater aquariums. The cause of the disease is unknown, but it is believed to be a viral or bacterial infection. The affected fish will have red patches on its body and may eventually become paralyzed. There is no known cure for this disease.
  • Viral Haemorrhagic Septicaemia: The guppy fish is infected with a virus that causes viral hemorrhagic septicemia (VHS). Lesions on the body are the first symptoms of viral hemorrhagic septicemia. Ulcers and sores will emerge later, as well as decaying fins. Pale gills and protruding eyes might be indicators of VHS. The fish will eventually cease eating and become less vibrant in color. You can treat your fish with antibiotics such as Maracyn 2 and API Furan 2 to cure VHS.
  • Popped eye: As the name suggests, popped eye is when the fish's eyes bulge out of its socket. It can be caused by a variety of things, including injuries, tumors, and infections. If the cause is an infection, it is often accompanied by other symptoms such as cloudy eyes, ulcers, and sores. Without knowing the root of the problem, it is very difficult to administer a cure. Different treatments might do more harm than good if you're not careful.


If your fish is displaying any of the following symptoms, it may be sick:

  • Loss of appetite
  • Rubbing against objects in the tank
  • White spots on skin or fins
  • Redness or inflammation
  • Ragged or torn fins
  • Difficulty breathing
  • Hiding
  • Bloated abdomen
  • Pinecone-like scales
  • Discoloration

If you notice any of these symptoms, it is important to take action immediately. The sooner you identify the problem, the easier it will be to treat.


Preventing illness in your fish is always easier than treating it. Here are some tips to help you keep your fish healthy:

  • Quarantine new fish before adding them to your tank
  • Maintain good water quality
  • Avoid injuries
  • Feed a varied diet
  • Remove sick fish from the tank immediately
  • Avoid overcrowding
  • Check fish for parasites before buying them
  • Add live plants


The best way to prevent your fish from getting sick is to maintain a clean and healthy aquarium. However, if your fish does become sick, there are a variety of treatments available.

  • Aquarium salt: Aquarium salt is a natural remedy that can be used to treat a variety of illnesses, including ich and velvet. Simply add 1 tablespoon of salt per gallon of water. The salt will kill the parasites and help to heal the fish.
  • Medications: There are a variety of medications available to treat fish illnesses. Be sure to read the instructions carefully and follow them exactly. Overdosing your fish can be just as harmful as not treating them at all.
  • Quarantine: Quarantining new fish is the best way to prevent the spread of disease. Keep new fish in a separate tank for 2-4 weeks before adding them to your main tank. This will give you time to observe them for any signs of illness.
  • Water changes: Water changes are an important part of maintaining a healthy aquarium. Be sure to change 25-50% of the water every week. This will remove any toxins or parasites that may be present.

Leopard Guppies Breeding

Leopard guppies are one of the easiest fish to breed and are perfect for beginners. However, there are a few things to keep in mind if you want to breed Leopard guppies successfully.

Here are some tips for breeding Leopard guppies:

Select Healthy Fish

Remember to take into account the number of fish you want to breed, as well as each fish's unique coloring and tail shape. If you select two fish that share similar color patterns, their fry will likely have that same pattern. The same goes for fin shapes.

Select Breeding Tanks

You'll need a 10 to 20-gallon tank with a heater and a gentle filter. Because the baby guppies (which are known as fry) can be drawn up the filter and killed if the filter is too strong, you want it to be mild. If you believe your filter's strength is excessive, cover the hole in the mesh with sheer tights. The tights will allow water to pass through while also protecting the fry from being aspirated.

Set Up The Breeding Tank 

Unfortunately, male guppies may become cannibalistic, therefore the fry will require hiding places after they are born. The guppy fry tends to sink, so use low-floating plants for their concealment. Because the healthy fry is rising up, an additional high cover is required. There should be no substrate in the tank. Substrates are rocks/imitation rocks used to cover the bottoms of fish tanks. A tank with a clean bottom can help fry grow because it cleans easily and you can keep track of how many live fries or how much they consume.

Adjust the Tank for Your Fish's Specific Requirements

While the females and males are in the tank together, set the temperature to about 77-79 degrees Fahrenheit (25-26.11 C). Purchase food with a higher nutritional value before putting the guppies in the breeding tank to encourage healthy reproduction.

Add the Guppies to the Breeding Tank

The only thing left to do now is wait for your fish to breed. When you see that your female fish is pregnant, put the male back in the regular tank. You can tell if a female fish is pregnant by looking for a dark mark on her abdomen; this is called a gravid spot. All females develop this when pregnant, but it's noticeably darker when eggs have been fertilized.

Know When Your Fish is About to Give Birth

The average gestation period is 26 to 31 days. However, there are some tell-tale signs that mean your female guppy is almost ready to give birth: a large stomach, a deep black gravid spot (or dark maroon if you are breeding albino or blond guppies), and her belly will start to look more like a box than round. It's important to remember that guppies give birth to live young rather than eggs. You'll need to keep a close eye on your pregnant female so you can remove her from the tank immediately after she gives birth (if you don't, she may eat her babies.)

Leopard Guppies Fry Care

You should start to see fry within a few hours after the female gives birth. The fry are born fully formed and able to swim, but they are very small (about 1/8 of an inch or 3 mm). They will hide among the plants in the tank and eat microscopic organisms. After about two weeks, you can start feeding them baby brine shrimp or powdered fry food.

As the fry grows, you will need to move them to a larger tank. Once they reach about 1/2 an inch (1.27 cm), they can be moved to a 10-gallon tank. You can then start feeding them regular guppy food.

By the time they are 2-3 months old, they should be the same size as their parents and ready to breed.
