Discosoma mushroom Corallimorphs have a smooth texture and are one of the most diverse in terms of colors and patterns. They come in every color imaginable and make a great choice for beginning reef hobbyists. They are easy to care for and easy to propagate. These mushrooms can even be kept with some angel and butterfly fish that would otherwise eat coral. While most aquarists do not go out of their way to feed these mushrooms, one can feed them by reducing the flow in the aquarium and allowing food to settle on their oral disk. They will close on the food and quickly ingest it.
