Category: Fish and corals nutrition

Feeding fish and corals is not as easy as it might seem. To ensure proper health, development and reproduction of your chosen species you must know its nutritional demands. In the wild, fish feed on molluscs, crustaceans, fish, plants and algae and other foods. These foods differ in terms of quality and quantity of nutrients. Additionally, the diet of fish can change as they grow and some fish can be 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 and corals nutrition, in an aquarium you will not have the ability to replicate their natural diet. You can, however, choose foods to make your fish’s diet as varied as possible.
