They are hardy and moderately easy to maintain, and under the right conditions, will multiply and spread very rapidly. In general, they need a medium light level, and should be placed lower in the tank if the light intensity is high. The Actinodiscus Mushrooms prefer a low to medium water flow within the aquarium, although different species may have different requirements. They are semi-aggressive and require adequate space between themselves and other corals and sessile invertebrates.
