Since they are , discus will generally eat all kinds of live food and need to be offered a variety. Other good foods include frozen brine shrimp, bloodworms, and some will enjoy whiteworms.

In addition, some discus will even enjoy eating a small amount of vegetable based foods such as spirulina, lettuce, or blanched cucumber. Give these foods a try and if you find that your discus likes them, be sure to supplement their diet with them on occasion.
