What Are Guppies?

What Are Guppies

Known sometimes by their scientific name, Poecilia reticulata, guppies are small tropical fish that are found in many parts of the world. They also one of the most common fish that people keep as pets in their home aquariums.

Guppies are very small compared to other fish, ranging from 0.6 to 2.4 inches in size and less than one gram in weight. As for their physical characteristics, guppies are most known for their colorful scales and flowing fins. In fact, guppies come in a variety of colors, including yellow, orange, blue, red, green, pink, and even multi-colored.

These shy fish often live in large groups called schools in order to protect themselves against all of nature’s predators, including bigger fish and sea birds. In general, guppies prefer a freshwater environment, however, they can easily adapt to brackish waters.

Guppies can be found in streams and shallow waters around the world – mainly in the waters of South America, Antigua, Trinidad, and more – as well as in the tanks of fish owners around the world.

What Do Guppies Eat in Captivity?

As the owner of guppies, you’ll find that it is best to feed them a combination of fish food, including flakes, freeze dried foods, and vegetation, to provide them with all the minerals and vitamins that they need.

While feeding them a combination of different types of food, you should make sure to only feed them a small amount of food. Guppies have much smaller stomachs than most fish, so overfeeding them can cause discomfort and block their intestines. It is best to feed them in small quantities.

Here are some more details on the foods they should be eating in captivity, to make sure they have a well-rounded and healthy diet.

Fish Flake Food

For guppies that live in captivity, the main component of their diet is fish flake food. But you won’t necessarily want to feed them just any flake food. Your flake food options for your pet guppy are flake food made specifically for tropical fish or a quality flake food.

Because guppies are so small, you should always avoid feeding them pellets.

Freeze-Dried Foods

There is a variety of freeze-dried foods that can be fed to guppies in captivity, including brine shrimp, bloodworms, and daphnia. Freeze-dried foods are a great option for adding variety to your guppy’s diet.


Because guppies are omnivores, plants and greens are a big part of their diet. So, adding vegetation to the diet of a guppy in captivity will give these fish additional nutrients that they may not get from the flake food.

This is a great thing to keep in mind when deciding on what you want to feed your own guppies in captivity. Some vegetation to consider adding to your pet’s diet include lettuce, peas, green beans, cabbage, kale, and cucumbers.

What Do Guppies Eat in the Wild?

What Do Guppies Eat in the Wild

As omnivores, wild guppies eat both plants and meat. The main components of their diet include plant particles, and insect larvae. The eating habits of guppies in the wild depend on the availability of food in their habitat.

Live food can provide a great source of nutrients for guppies in the wild. When available, guppies can often feed on other species like brine shrimp, invertebrates, and insect larvae. Mosquito larvae is an especially great meal for them, as it allows these fish to not only get their nutrition, but also naturally control the population of mosquitos while slowing the spread of malaria.

In the wild, guppies forage, or search, for food in large groups called schools. When the group comes across algae, this just means there is more nourishment to go around.

What Do Baby Guppies Eat?

Baby guppies, also called “guppy fry,” are only one fourth of an inch, or 0.6 mm, in length. Because of this, caring for baby guppies is completely different than caring for fully grown guppies.

Because they are much smaller in size compared to adults, baby guppies can only eat certain foods like crushed fish flakes, frozen dry food, daphnia, or baby bring shrimp. The key thing to remember when feeding baby guppies is to only give the foods that are small enough for them to properly digest.

How Often Should You Feed Guppies?

How Often Should You Feed Guppies

To be healthy, adult guppies should eat once to twice a day. Baby guppies, however, need to eat more often than adults. Young guppies should eat somewhere between six to eight small meals per day because they need more energy to grow.

It is important not to overfeed these tiny fish, so you should only feed them as many flakes that they can eat in two minutes. Overeating can cause health issues in their small stomachs and can block their intestines.

Uneaten food can release toxins in the water. So, after they finish eating, you should be sure to remove any uneaten food from the water with a net. This will help you maintain the health of your tank and clean high-quality water.

Tips for Caring About Pet Guppies

When buying guppies as pets, you’ll want to create a comfortable environment and tank for them. Although guppies can be found in different bodies of water like streams and ponds, those living in captivity prefer freshwater tanks.

Check out these tips for setting up your home aquarium and maintaining a comfortable environment for your guppies.

Abide by these tank requirements

When picking out a tank, it is recommended to start with a minimum of 10-gallons – the most common starter size tank. Anything less than 10 gallons will be too small, making it too difficult to keep clean.

When putting your tank together, you’ll also need to add about two inches of gravel at the bottom of the tank. The gravel will mimic their natural environments in the wild. This will not only add a layer of décor to the tank, but it will also help filter the water and keep it clean.

Decorate your tank to give your guppies enough room to hide

One of the biggest things to keep in mind when setting up your tank is to make sure it is big enough to have plenty of spots for your guppies to hide. So, in addition to adequate size tank, you should also decorate the inside of the tank with décor that can double as a hiding place for your guppy, like plants, ornaments, caves, and structures.

Live plants can be a great addition to your tank, providing both coverage and the perfect hiding spots for your fish. Think about adding a variety of live plants, such as Java moss, flame moss and wisteria. These plants will also serve to keep the water clean through natural processes and cycles.

Keep a warm and comfortable temperature

Water temperature is critical in your guppy tank. It is very important to keep an ideal temperature for your guppies to thrive. If the tank temperature is too hot or too cold, you’re at risk for killing your fish.

An ideal tank temperature for guppies is between 74 to 82 degrees Fahrenheit, or 22 to 28 degrees Celsius. This will most closely mimic the tropical waters that they are native to.

Add smaller fish to keep your guppies companyAdd smaller fish to keep your guppies company

Guppies are friendly fish, and they can usually get along well with other species of fish. However, the other species of fish that you add to your tank should be small in size and calm in their nature so they can get along well with the guppies.

Even though guppies are small enough to be the perfect prey for many predators in the water, there are some types of fish that can live in peace and harmony with guppies in the same tank. Specifically, smaller fish like platys or gouramis make great companions for guppies.

Here is a list of other fish species that can make great companions for guppies.

  • Cardinal tetras
  • Mollies
  • Zebra danios
  • Cory catfish
  • Swordtails
