Rhodactis inchoata
A small corallimorph best known from Tonga. Short tentacles ring the margin of the disc and small papillae cluster in the centre. Traded specimens show blue, red-purple or green ground colours with a contrasting mouth area.
Rhodactis inchoata is a corallimorph of shallow western Pacific reefs, described by Carlgren in 1943; WoRMS lists its English names as blue mushroom anemone and Tonga blue mushroom anemone. It builds no calcareous skeleton. Short tentacles ring the margin of the disc while small papillae cluster densely in the centre. Specimens traded for aquariums show blue, red-purple or green ground colours with a contrasting mouth area, and those whose surface vesicles inflate into spheres are sold as bounce mushrooms at high prices. That trade name is applied to several Rhodactis species, however, and is not a character unique to this one. It reproduces asexually by fission and will multiply in the aquarium. Symbiotic zooxanthellae supply part of its nutrition through photosynthesis. Having no skeleton, it is not covered by the CITES coral listings.

LiveAquaria lists Rhodactis mushrooms as low to moderate light corals. Strong light makes them shrink and lose colour, so raise light levels gradually.
LiveAquaria gives placement as bottom and flow as low to medium. The disc opens best on low rockwork or a frag rack in gentle flow.
Water 24-26C, specific gravity 1.023-1.025 (salinity 33-35 ppt), pH 8.1-8.4, KH 8-12. Iodine, magnesium and trace elements are recommended. It tolerates modest swings in water quality.
It can be kept on zooxanthellae alone, but feeding micro-plankton or brine shrimp to each disc speeds growth and division.
LiveAquaria rates Rhodactis as semi-aggressive, so leave clearance from neighbouring corals. Bounce is a trade name covering several species, so identification by that name alone is unreliable.
Beginner. This is a beginner-friendly species. No special equipment or experience is required, and it can be kept successfully with basic care setup.
The ideal temperature for Bounce Mushroom (Rhodactis Inchoata) is 24〜26℃. Avoid sudden temperature changes and maintain a stable environment.
Bounce Mushroom (Rhodactis Inchoata) feeds on: Nutrition from its zooxanthellae, supplemented by micro-plankton, brine shrimp and similar foods.. Aim for a balanced diet with appropriate feeding frequency.
