Many tropical fish are herbivorous, meaning they eat plants and algae in their natural environment. Eating plants is much easier for your fish to digest than dry food.


Dry Foods

Fish keepers often feed their tropical fish dry foods that have been specially designed for them; these will meet all their nutritional needs when stored properly.

These include flakes, micro-pellet and granulated fish foods. They’re great for providing variety to your pet’s diets and some are even tailored towards specific species like herbivorous fish or bottom feeders.

Tetra flakes are a popular fish food option that offers high protein content and essential vitamins to support the immune system. Not only are they easy to digest, but they don’t leach color from the water either.

Another popular tropical fish food is Tetra Veggie Algae Wafers, an all-vegetarian diet. This fish food contains Omega-3 fatty acids to boost immunity and shield against stress or disease.

This fish food is specially formulated with shrimp that various fish species enjoy, plus it includes stabilized Vitamin C to improve the color of your pet fish. Made from all-natural ingredients, it works effectively to enhance the hues of most tropical fish.

Frozen Foods

Frozen foods are an ideal way to provide your tropical fish with a nutritious diet. They’re made from whole ingredients that have been flash frozen to maintain their original nutrients and eliminate any pathogens.

Frozen food, unlike dry food, does not contain preservatives or artificial colors. Furthermore, it’s more cost-effective and easier to store than live food.

When it comes to frozen foods for fish tanks, brine shrimp and bloodworms are two of the most popular options. Both are high in protein and make an ideal addition to any tank’s diet.

They come in individual cubes or large frozen slabs that can be broken apart to form smaller pieces. Some even come encased in blister packs to keep them fresh and free from contamination.

Fruits & Vegetables

Fruits and vegetables are essential components of a fish’s diet. They provide essential nutrients, vitamins, and minerals that promote good health, growth, and development in your aquatic friend.

Fish generally enjoy eating apples, grapes, bananas, pears, mangoes, strawberries, oranges, raspberries and watermelon. Feed these fruits in small amounts so as not to clog the filter or make it difficult for you to remove them from your tank.

Vegetables can be incredibly beneficial to tropical fish. They contain vitamin A, B6, C, iron, fibers, potassium and magnesium in abundance.

Most fish will benefit from adding vegetables to their diet. Some species, such as Pacus, Silver Dollars, Mollies, Farowellas and twig catfish are mainly vegetarian while many others like Goldfish or Guppies enjoy adding veggies into their meals.

Some vegetables can be fed raw to your fish, but most should be blanched prior to offering. Blanching will make the vegetables soft and easy for your fish to consume.


For maximum nutritional benefit in your fish’s diet, supplements are an ideal solution. They not only promote healthier skin and stronger teeth for your aquatic friend, but they can also give their color more vibrancy as well as help fight off disease and parasites!

Many people rely on generalized flakes and pellets when feeding their fish, but it’s essential to remember that different species require specific nutrients. Surface feeders benefit from flakes or floating pellets while middle and bottom-dwellers need food that sinks quickly and can be compressed into ‘tablets’ for ease of access.

Supplementing a tropical fish’s diet can be done through frozen foods like krill, bloodworms and plankton; or freeze-dried meaty prey like daphnia or brine shrimp that mimic what fish would consume in the wild. Since these products contain less live bacteria than live foods do, adding supplements from safe sources and using them properly are ideal! If you decide to add supplements into your tropical fish’s diet be sure they come from reliable sources and that they’re used properly!
