If you want to keep rainbow fish, there are many things to take into consideration. If you want to keep healthy and good looking rainbow fish, you must provide them with an environment and diet akin to what they are used to from the wild. Keeping rainbow fish in an unsuitable environment and giving them “normal flake food” will almost always lead to ulcers and premature death. When aquarists place rainbow fish in their aquariums, they often give them ordinary flake food with a low algae content. Even a really good high-quality flake food is however normally a bad choice for rainbow fish, because the composition of most “general” flake foods is tailored for omnivore fish that eat more meaty food and less algae food. A diet rich in protein and low in fiber is not healthy for rainbow fish and will increase the risk of various health problems. Rainbow fish will eat practically anything you give them, but that doesn’t mean that it’s healthy for them. A key element in keeping Rainbow fish healthy is therefore to provide them with a diet that is similar to what they would eat in the wild. Wild rainbow fish feed mainly on algae and other plants, but also eat aquatic insects, terrestrial insects, tadpoles, crustaceans and really small fish. A majority of their diet is however always made up by algae. Staying away from all sorts of meaty food is however not a good idea. As mentioned above, wild rainbow fish feed on insects, crustaceans, small fish, etcetera. This means that they need a certain amount of meaty foods in the aquarium as well. The meaty food should however never make up more than 35-40% of the diet, and fatty food should be avoided altogether. You can for instance give your rainbow fish mosquito larvae, fruit flies and fish fillets. Stay away from food types that the rainbow fish could never obtain in the wild, such as beef heart.
