The Frilly Bounced Mushroom is a member of the Rhodactis
genus, formerly called Discosoma
. It generally grows larger and has shorter tentacles than other mushroom corals.
The Frilly Bounced Mushroom is easy to maintain in the reef aquarium, and a good choice for the beginner hobbyist. It is somewhat aggressive, however, and can harm sessile invertebrates and overgrow other inhabitants of the reef. It requires a low to medium light level combined with a medium water movement within the aquarium.
It may reproduce in the home aquarium provided that water conditions are adequate, sometimes causing over-population. A small portion of the base or mouth will separate from the parent polyp and grow into a full-sized mushroom within a few months.
The symbiotic algae zooxanthellae hosted within its body provide some of its nutritional requirements, but it also eats plankton and some larger organisms.
