Mushroom Softies in general are distinct from all other coral by their oral disc shape. They have an umbrella shaped flat or circular disc surrounding the opening or mouth, and unlike other corals that have flat or concave mouths. On their discs, they have tentacle that look more like little bumps. This textural and shape combination gives the Actinodiscus Mushroom an uncanny resemblance to the popular dry land mushroom; oyster mushrooms.
The Rhodactus Mushrooms come in a wide array of colors, textures, and patterns. They range in color from solid to striped to spotted, and their textures range from silky smooth or stubby coarse.
These mushrooms are hardy and arguably the easiest soft coral to maintain. Under right conditions, they will multiply and spread relatively fast. In order for them to flourish they need;
1. Exposed to consistent medium light level.
2. Low to medium water flow within the tank, although different species may have slightly different requirements.
3. Temperature that fluctuates between 77 to 80 degrees Fahrenheit.
4. Salinity of between 1.025 to 1.027.
It is also important to note that these splendid species are somewhat aggressive and will require adequate space between themselves and other corals and sessile invertebrates you might have in your aquarium.
An Rhodactus Mushroom obtains a great deal of its nutritional requirements through the photosynthesis of the symbiotic algae zooxanthellae which it hosts. It also feeds on other matter and benefits greatly from additional feedings in the form of micro-plankton or brine shrimp fed to each polyp individually throughout the colony.
These corals reproduce by utilizing a form of asexual reproducing process called ‘budding’.
