Likely Reef Tank Suitable
Likely Fish-Only Tank Suitable
Range: Tropical Western Atlantic Ocean: Southern Florida to Brazil, Gulf of Mexico, and the Caribbean.
Natural Environment: Usually found encrusting substrates of various kinds (rocky areas and dead coral rubble) in very shallow coastal environments where currents are fairly swift.
General Husbandry: The Ricordea family contains only two members, the species described here, and R. yuma hailing from the Tropical Indo-Pacific. Both have surface areas that are usually covered with short, bubble-like tentacles. Both are also fairly shallow water members and need strong light and swift water movement. Those are requirements opposite of those other members in this Order.
These mostly photosynthetic corals are among the easiest of all corals to maintain because they do better in somewhat nutrient rich surroundings. Most attain a size of approximately 2 - 3 inches (5 - 7.5 cm) in diameter. Keep in mind they neither are not true anemones nor are they true corals, however, they are somewhere in between or more appropriately a comparative anatomy or simply put, a morph.
The majority of its nutrition comes from its ability to photosensitize; nevertheless, this animal has short tentacles and is also a suspension feeder. As with any animal with tentacles, they can be directly fed and have responded nicely to zooplankton-like foods such as Cyclop-eeze and baby brine shrimp in my aquariums.
Generally hardy, disease resistant, and fairly fast growing, however, can damage other corals if they touch them, therefore allow sufficient space between it and other corals.
Iodine additives, used as their manufacturers recommend, also seem to have a positive effect on these so-called "mushroom" corals.
