The Actinodiscus Mushrooms are also referred to as Mushroom Anemones and Disc Anemones. They were previously in a genus called Discosoma. These invertebrates display a wide variety of colors, textures, and patterns. Some are solid colors, such as the blue specimen pictured above, whereas, others are striped or spotted. The taxonomy of the various species is in a state of flux, and will probably continue to change.
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. Each ships as several individual mushrooms attached to one rock.

An Actinodiscus Mushrooom receives some of its nutritional requirements through the photosynthesis of the symbiotic algae zooxanthellae which it hosts. It also feeds on other nutrients and particulate matter and benefits from additional food in the form of micro-plankton or brine shrimp fed to each polyp of the colony.

In our aquarium store I saw severall of these mushrooms unattached. I got 5 of them together with a different bigger mushroom. Unfortunately the small ones have dissapeared almost all, except for this one. But who knows what we find in a few months.

Besides this one I think I saw one between the purple mushrooms above this one and one next to the soft coral

They seem to be popping up everywhere now. Besides the one already in the pictures there is one between the purple mushrooms above and one underneath the soft coral. Also I found one which is now in a shot glass in the RSM because of vacation. He will hopefully be part of a first start of a new mushroom rock, there is already a purple and red one attached.
