Care
Cycloseris cyclolites is a small, free-living disc coral in the plate coral family. It is a round, slightly domed single polyp with fine radiating ridges and short tentacles, and it is popular for its bright colours (greens, reds, oranges and multicoloured forms). It is not sold by name at LiveAquaria; the care below draws on its short-tentacle plate coral listing (Fungia), a close relative in the same family. Placement: on the sand bed, ideally fine sand, where it can move about. Moderate light and low to medium flow suit it. It can inflate with water and right itself if turned over. Water: alkalinity dKH 8–12, pH 8.1–8.4, with calcium, strontium and trace elements kept up. Growth is slow. Selling: this is a CITES Appendix II coral. Frags grown in the UK can be sold freely; wild-collected or imported pieces must have been legally imported with CITES paperwork.

Diet
Photosynthetic, but feeding a few times a week with small meaty foods such as mysis or brine shrimp helps. Only feed when the polyp is extended.
Breeding
Not normally fragged. Plate corals sometimes produce small daughter discs (anthocauli) from the parent or from damaged pieces, which can be grown on.
Compatibility and tank mates
Semi-aggressive: even short tentacles damage corals they touch, and it can move across the sand into neighbours, so keep space around it. Some fish and hermit crabs may pick at it.
