Category: Fish nutrition

Feeding fish is not as easy as it may seem. To ensure proper health, development and reproduction of your chosen species you must know its nutritional demands. In the wild, fish feed on insects, molluscs, crustaceans, fish, plants and algae. These foods differ in terms of quality and quantity of nutrients. Additionally, the diet of fish can change as they grow and as the season changes. Moreover, some fish can be particularly picky. On the other hand, in the absence of their basic food, fish turn to less tasty substitutes, which they have avoided so far. Even with a vast knowledge of fish nutrition, you will never have the ability to replicate their natural diet in the tank. You can, however, choose foods to make your fish’s diet as varied as possible.

Our experts will tell you how to feed fish, what type of food to choose and what interesting food ingredients you should pay attention to. You will learn how the health and condition of fish is affected by algae and what crustaceans contain. You’ll also know all sorts of interesting facts about Tropical foods and probiotics’ role in fish nutrition. We can assure you that fish nutrition will no longer be a mystery to you.
