Different Fish, Different Foods


Feeding your fish the correct diet is vital to ensure they grow in health and well-being. There are dry, frozen and live foods available for all types of fish.

Generally live foods are thought to be the most beneficial as they are the fishes natural diet and of course provide exactly the right amount of nutrients. However, they can be time consuming and run the risk of diseases and infections. Dry food can be easier and quicker to use. It’s also easier to store, and can be kept at room temperature. With today’s modern science and technology, most dry foods compare favourably with a live food.

Looking at some of the most popular types of fish and the food that is best for them will help you to make the best choices to ensure that your aquarium always looks its best. Choosing your fish food from Swell UK will offer you the best choices at the very best prices.


This cold water species is pretty easy to feed as it doesn’t require a specialised diet. Flaked or dry food contains all of the minerals and vitamins that they need. However, you can feed them a live food of brine shrimps, daphnia or bloodworms.

All of these should be bought from a reputable retailer as they can carry infections and diseases that can harm your fish. This type of food can also be bought frozen or freeze dried, which lessens the chance of any harmful bacteria.

Catfish and Other Bottom Feeders:

Catfish and other bottom feeders will scavenge along the bottom of the tank to feed. They will eat dead fish matter and plant waste including algae.

They require a specialised sinking food that will travel directly to them. It needs to have a high vegetation and vitamin C level to echo their natural diet. A ready-made pellet will contain all of the necessary elements, and is often in a pellet or wafer form that does not dissolve quickly.

Discus and other carnivorous fish:

Discus are known grazers and will spend all day looking for food. It’s important to make sure that they have enough to maintain their health and enhance their beautiful tropical colours.

They can be fed a ready-made food made from krill and silkworm pupae, their natural food source. Many of these foods are made to look ‘worm like’ and will slowly sink, to promote natural feeding habits. Of course live and frozen foods can be given too if you prefer. Very young discus will benefit from a diet of brine shrimp to encourage healthy growth.

Some tropical fish eat a mostly vegetable based diet and can be fed a dry food that contains the right amount of vitamins, proteins and minerals to make sure that they are in perfect health. Evidence that they are on the right food will be seen in their condition. Bright, vivid colours and an active disposition will indicate that your fish are in the best health.

It’s important to not over feed your fish, as this can increase the amount of fish waste and raise ammonia and nitrite levels in the tank. Feeding a little and removing uneaten food after about 5 minutes will keep your tank clean and your fish healthy.

Of course there are many species of fish and some require a specialised diet. Speak to a fish specialist or vet for the best nutrition advice.
