Mushroom coral, called Actinodiscus or Discosoma, is soft coral with no exoskeleton. It grows on rock and has a short stem with a cap, somewhat resembling a mushroom. Mushroom corals grow in a variety of colors and textures, and look beautiful in an aquarium. Because mushroom corals are very hardy, they are easy to maintain in an aquarium. However, they reproduce somewhat aggressively and can overtake an aquarium if you don't prune them out now and then. Leaving even a small piece of the coral in the aquarium will lead to a new infestation. If there are too many mushroom corals the other corals in the aquarium can suffer.
