Introducing the Lyretail Guppies: The Perfect Beginner Fish for Your Aquarium!

Guppies are one of the most popular fish for beginners due to their bright colors and easy-going personalities and the Lyretail Guppies are no exception! These little fish are perfect for small tanks and can even be kept in bowls. They are peaceful and relatively easy to care for, making them ideal for first-time fish keepers.

The Lyretail guppy is a fish that will add both color and excitement to your aquarium. They are known for their unique tail shape and vibrant colors. No two individuals are alike, as each one's colors fingerprint-like.

This species is originally from Central and South America, but it has been introduced to many other countries in order to help fight malaria by eating mosquito larvae.

Lyretail Guppies Care

Lyretail guppies are livebearers, meaning their offspring develop inside them and are born alive. These fish come from Central and South America. Lyretail Guppy's natural habitat is slow-moving streams with plenty of vegetation where they feed mainly on small invertebrates, detritus (decaying organic matter), and occasionally fish eggs.

Lyretail guppies are quite resilient and can withstand living in water that is not the cleanest; however, they will be much healthier and their colors will be brighter if the water quality is maintained. Ammonia and nitrite levels should ideally be at zilch because these pollutants have the ability to kill fish very rapidly. If at all possible, nitrate levels should also remain low. Lyretail guppies can tolerate high temperatures as well as oxygen-less periods of time in their habitat.

For optimum health, water changes should be done regularly for Lyretail guppies. Like all fish, diet plays an important role in their success. While they're not fussy eaters, a diet rich in live foods will bring out the brightest colors and help them develop properly. A good quality flake or pellet food can be used as the main dish with live foods such as brine shrimp or daphnia added for variety. When choosing your Lyretail guppy group, always go for healthy-looking fish with bright colors and clear eyes. The ideal number of guppies is two males for every one female, but if you are unable to maintain a group environment, then keep a minimum of two guppies together. Some other peaceful fish that make good tank mates with Lyretail guppies include mollies, platies, swordtails, Endler's livebearers, Girardinus species, and Heterandria species.

Lyretail Guppies Size 

Although the average Lyretail guppy only grows to be 2.5 inches, with proper care they have the potential to reach 3 inches in length. To ensure your guppies grow to their full size, it is important that they are well cared for and provided adequate hiding places and quality food. Not meeting these conditions can lead to stunted growth in your fish.

Lyretail Guppies Lifespan

While the average lifespan of a Lyretail Guppy is only 2 years, with proper care and diet, some fish have been known to live for 3 years or more. However, most guppies will not live longer than 2 years without stress factors.

Lyretail Guppies Appearance

These fish are usually only 2.5 inches, yet have teeth in both their upper and lower jaws. Furthermore, they come in a wide variety of colors and coloration patterns; In fact, no two individuals look alike. While wild specimens tend to be gray with a few tints of coloration, years of captive breeding have led to strains of intense color coming in many different forms like blue or orange.

There are also 12 tail fin varieties: round tail, pintail, pointed or spear tail, swordtail, lyretail, spade tail, flagtail, veil tail, fantail, and triangle tail. The color of the tail is what defines the fish’s name even if the body is of different coloration, for example, if the body is red and the tail is blue then it is called a blue Guppy. It is scarce to find wild specimens for sale, in most stores, there are only inbred guppies, usually, these have a more fragile health. Regarding the Lyretail Guppies, these are silver, green and red with a white tail fin.

Lyretail Guppies Behavior

The next fish species are famous for being social creatures, making them ideal friends for other tank mates. They get along well with others and typically avoid conflict.

Lyretail Guppies love to explore and are social by nature, so they commonly reside near the surface of their tank. However, when they're not busy swimming around or interacting with other fish, you can find them hiding among plants or other decorations in their tank.

Although aggression is common among Lyretail guppies during mating season, it typically isn't a cause for concern as long as the fish appear to be otherwise healthy mates. If you notice any aggression outside of the mating season, it could be a sign that the fish are stressed and you should take steps to address the issue.

Lyretail Guppies Tank Setup

Although it's not tricky to set up a freshwater aquarium for Lyretail guppies, there are some things you should remember, especially if this is your first time keeping fish.

Tank Size 

The Lyretail Guppy is a freshwater fish that requires 5 gallons of water to thrive, which is comparable to the amount other guppy breeds need. They can grow up to 2 inches in length. Even though they are social creatures by nature and prefer living in groups, it's okay to house just one if you'd like. However, because their markings look similar to others of their kind, they may not be as easily distinguishable and could become stressed out or bullies when placed with other fishes in a new environment. If you have the space for it, we recommend housing at least 3-5 Lyretail Guppies in a 20-gallon tank so that they feel more comfortable and secure swimming around the home.

Water Condition

Lyretail Guppies are tropical fish that do best in warmer waters of 77 to 80 degrees Fahrenheit (25-27 Celsius). However, they're very adaptable fish as well, able to live and prosper even with changing weather conditions present in their natural habitats. For example, they can withstand temperatures as low as 63°F (17°C), but when breeding, you must maintain higher levels. You may require a heater to keep the pH level at 7.0 to 8 during reproduction. Water hardness should be between 8 and 12 dGH for optimal results.


The key to a healthy fish aquarium is clean water, and the best way to achieve that is by using a filter. There are several types of filters available for purchase, so it's important to do your research before making a decision. Some common types of filters include canister filters, power filters, and hang-on-back filters. Canister filters are more expensive but far more efficient, lasting a long time. Power filters are less expensive to purchase, but they must be replaced more frequently. Hang-on-back filters are an excellent middle ground - they're not as pricey as canister filters, yet they last longer than power filters.

In addition to a regular filter, you might want to invest in one that has a UV sterilizer. This will help clean the water and get rid of bacteria.

Tank Decor

There are many options when it comes to decorating your Lyretail Guppy tank. These fish are not fussy and will do well in most setups.

However, keep in mind that Lyretails enjoy swimming near the surface of the water, so you'll want to make sure there's plenty of open space for them to swim around. Some people like to put live plants in their tanks, which can provide hiding places for the fish and help to maintain the tank clean. If you decide to include live plants in your aquarium, check with an expert first. Some plants need special attention and may not thrive in your aquarium.

Rocks, driftwood, and artificial plants are other popular tank decorations. The bottom of the tank may also be covered with gravel. When it comes to decorations, be cautious of anything that is sharp or may harm the fish.

Although Lyretail guppies do not require specific lighting, you will need to give them enough light for live plants (if you choose to include them in your tank). Fluorescent tubes or LEDs would be ideal. Make sure the light you buy is specifically made for aquariums and does 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.

While Lyretail guppies are beautiful fish, it's important to do your research before adding them to an existing tank. Make sure to pick other fish that will get along well with Lyretails, as they can be aggressive. If you find that the Lyretails in your tank is not getting along with others, you may have to remove and rehome them.

Lyretail Guppies Diet

Lyretail 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 or tank, you have at home, you can feed your Lyretail guppies a variety of food such as

Fish flakes: high-quality Many brands of fish flakes are available, both at local pet stores and online. Be sure to select a brand that is designed for freshwater fish specifically. Doing so will ensure your pet receives the best possible nutrition. Some common brands include Tetra, Wardley, and Hikari.

Granules are similar to fish flakes but are a bit larger in size. They're a good option for Lyretail guppies that are a bit larger. Granules are rich in nutrients and will help keep your fish healthy. Some Most common brands include API, Tetra, and Hikari.

Live food:
If you want your Lyretail guppies to stay healthy, it is best to feed them a combination of live and dry food. They love chasing and eating small insects such as brine shrimp, daphnia, and bloodworms. You can find live food at most pet stores. However, make sure not to feed your Lyretail guppies live food that is too big, as they may have difficulty digesting it.

Frozen food:
Frozen food is as nutritious as live food and is a convenient alternative. Frozen bloodworms, brine shrimp, and daphnia are available at your local pet store or online. Before feeding the meal to your fish, be sure to thaw it thoroughly.

Vegetables are an excellent source of vitamins and minerals. Zucchini, cucumber, and spinach can all be used to blanch vegetables for your Lyretail guppies.

Some things you should not feed your Lyretail guppies are:

  • Canned food: Canned foods are often high in salt and other ingredients that can be harmful to your fish.
  • Human food: Human food is not meant for consumption by fish and can make them sick.
  • Old food: Old or expired food can contain harmful bacteria that can make your fish ill.

Things to keep in mind while feeding Lyretail guppies:

  • It's best to feed your Lyretail guppies 2-3 times a day, in small portions.
  • You can use commercial fish food or make your own at home.
  • Be sure to remove any uneaten food from the tank after a few minutes to prevent it from polluting the water.
  • Never feed your fish in large amounts, as overfeeding can cause health problems such as obesity and swim bladder disease.
  • Make sure your Lyretail guppies have a varied diet to ensure that they get all of their required nutrients.
  • Lyretail guppies should not be regularly given live foods as they can cause health problems.

Lyretail Guppies Diseases

Guppies are healthy fish that seldom get sick. However, there are a few illnesses that they can get, so it's essential to be aware of them. Some prevalent diseases affecting Lyretail guppies include:

  • Ich: White spot diseases, also known as white spot ailments, are the most prevalent problem in the fishkeeping hobby. If Ich is treated promptly, it is not deadly. Ich is caused by an ectoparasite (ciliate protozoan Ichthyophthirius multifiliis) and can be recognized with little effort. The fish begin to rub their skin against rocks, plant leaves, decorations, or the aquarium's sides as a result of ich. You'll notice little white spots on your fish's skin and fins. It is not difficult to treat ick. There are several medicines accessible; however, aquarium salt may also be used.
  • Velvet: Velvet is a disease that affects the skin and gills of fish. It's frequently confused with ich, but there are some important distinctions to keep in mind. Velvet is harder to discover and typically only affects one side of the fish. The sick fish may have trouble breathing and will often hide if velvet isn't treated promptly. There are several treatments for velvet, but the easiest method to avoid it is by quarantining new fish before adding them to your aquarium.
  • Fin rot: Fin rot is a bacterial infection that affects fish fins. It's usually caused by poor water quality or injuries. The fish will have ragged or shredded fins if this condition is not treated. Left untreated, fin rot may be deadly. There are various medications available to treat fin rot, but the best method to prevent it is to maintain good water quality and avoid causing any problems.
  • Protozoan: Protozoa are tiny worms that mostly affect guppies; however, other fish may be harmed by them as well. The parasite attaches to the fish's skin and slowly crawls into its muscle until it reaches circulation. Protozoal infections are often seen in unheated tanks that have 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 a condition in which the abdomen becomes filled with liquid it cannot expel. The fish grows bloated, discolored, and deformed, with scales forming like pine cones from its body. If a fish's belly swells, it may have trouble swimming. Water pollution, genetic disease, or feeding habits might cause bloating of the abdominal cavity. Dropsy can be caused by overfeeding on bloodworms or chronic high stress.
  • Red Blood Paralysis: This is a condition that affects fish in brackish and saltwater aquariums. The disease's source is unknown, although it is thought to be a viral or bacterial infection. The diseased fish will have red spots on their bodies and may eventually become paralyzed. There is no known treatment for this illness.
  • Viral Haemorrhagic Septicaemia: The guppy fish can contract a virus called viral hemorrhagic septicemia (VHS) which causes lesions on the body. If left untreated, these ulcers and sores will worsen, sometimes leading to rotting fins. Other symptoms of VHS in guppies include pale gills, protruding eyes, and loss of appetite. You can treat your fish with antibiotics such as Maracyn 2 and API Furan 2 to cure VHS.
  • Popped eye: Puffed eye is characterized by the fish's eyes swelling out of their sockets. It can be caused by a variety of problems, including injuries, tumors, and infections. If the source of the issue is an infection, it usually comes with additional symptoms such as hazy eyes, ulcers, and sores. If you don't know what caused the problem in the first place, several therapies might do more harm than good.


The following are the symptoms of a sick fish:

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

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


Rather than treating your fish's illnesses, it is much easier to prevent them in the first place. Use these tips to maintain a healthy environment for your pet fish:

  • 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 keep your fish healthy is by keeping the aquarium clean and ensuring there's plenty of food. If your fish falls ill, you can try a couple of different treatments.

  • Aquarium salt: Use aquarium salt to treat your fish for illnesses such as ich and velvet. For every gallon of water, add one tablespoon of salt. The salt will act to kill the parasites while also helping the fish heal.
  • Medications: There are a number of treatments for fish illnesses. Make a careful study of the directions and procedures and follow them precisely. Overdosing your fish or not treating them at all can be equally detrimental.
  • Quarantine: The best method to keep new fish healthy is by quarantining them. Keep new fish in a separate tank for 2-4 weeks before introducing them to your main aquarium. This will provide you time to look for any symptoms of the disease.
  • Water changes: Maintaining a healthy aquarium requires water changes every week. The amount of water you should change depends on the size of your tank but ranges from 25-50%. This will remove toxins or parasites that might be present.

Lyretail Guppies Breeding

If you are looking to breed fish and have no prior experience, Lyretail guppies are a great species to start with. Although they are easy to breed in comparison to other species, there are still some best practices you should follow for a successful project.

Here are some tips for breeding Lyretail guppies:

Select Healthy Fish

Give some thought to which fish you want to breed and their coloring. If the parents have similar colors, it's likely their offspring will too. Another point to consider is the shape of each fish's fins.

Select Breeding Tanks

To keep your baby guppies healthy, the water temperature should be maintained at somewhere between 75 and 80 degrees Fahrenheit, which is equivalent to 24 and 26 degrees Celsius. Your tank will need both a heater and a fine filter. It's important that the filter isn't too powerful, as fry could be pulled up into it and suffocated. If you're not sure if your filter is too strong, try placing sheer tights over the hole in the mesh. This way, water can still flow through while also protecting any fry from being drawn up into the filter.

Your tank will also need some plants that can provide both hiding places and food for the fry. Guppy grass, Hornwort, and Java fern are all good options.

Set up the Breeding Tank

You'll need to provide hiding places for guppy fry, as male guppies may eat them once they are born. Guppy fry sink when they're first born, so use low-floating plants for their safety. The healthy fry will start to rise after a few days, at which point additional high cover should be provided. It's best not to have any substrate in the tank because it can make it difficult to see and count how many fries there are or how much they're eating.

Adjust the Tank for Your Fish's Specific Requirements

Before adding the guppies to the breeding tank, set the temperature to 77-79 degrees Fahrenheit (25-26.11 C). Also, be sure to give them high-nutrient food so their development will be healthy.

Add the Guppies to the Breeding Tank

The final step is to wait for your fish to breed. When you see that your female fish is gravid (pregnant), return the male to the typical tank. Look for a dark abdominal marking called a gravid spot; all females develop this when pregnant. If eggs have been fertilized, the gravid spot will be significantly darker than usual.

How to Tell When Your Fish is About to Give Birth

The average gestation period for guppies is 26-31 days, but there are some definite signs that your female guppy is about to give birth: a large stomach, deep black gravid spot (or dark maroon if you're breeding albino or blond guppies), and her belly will become more squared off than round. It's crucial to remember that guppies have live births rather than laying eggs. So, once she goes into labor, you'll need to keep close tabs on her so you can remove her from the tank as soon as she gives birth (if not, she might eat them.)

Lyretail Guppies Fry Care

Just a few hours after the mother gives birth, her fry is born. They're able to swim and hide amongst plants, but they'll only eat microscopic organisms for their first two weeks of life. Nevertheless, you can start feeding them baby brine shrimp or powdered fry food as soon as they're welcomed into this world.

As your fry grows, eventually you'll need to transfer them into a larger tank. Once they're about 1/2 an inch (1.27 cm), a 10-gallon tank should be enough room. At this stage, regular guppy food can become part of their diet. By two to three months old, guppies will likely be the same size as their parents and ready to mate themselves.
