The earth's oceans are filled with a diverse variety of fishes that feed on a wide range of marine plant and animal life. For this reason it is important to know what a particular fish type or species primarily eats in nature, so that when it is kept in a saltwater aquarium system you can provide it with the proper nutritional diet it specifically requires.
