Rhodactis indosinensis
A corallimorph whose disc is covered in short, hair-like tentacles. It comes in brown, purple, tan and green, spreads over rock by dividing, and builds no skeleton.
Rhodactis indosinensis is a corallimorph of shallow Indo-West Pacific reefs. Although related to the stony corals it builds no calcareous skeleton, consisting only of a disc-shaped oral disc. As its trade name suggests, the surface of the disc is densely covered in short, hair-like tentacles, and colour varies from brown and purple through tan to green. It reproduces asexually by fission and by laceration of the disc, and will spread over rock in the aquarium when conditions suit. Symbiotic zooxanthellae supply part of its nutrition through photosynthesis, and it makes up the rest by capturing plankton and larger food items. It grows in shallow water and in captivity prefers medium to high light with medium flow. It is somewhat aggressive, able to damage sessile invertebrates and overgrow neighbouring corals, so it needs clearance. Having no skeleton, it is not covered by the CITES coral listings.

LiveAquaria lists it as a moderate-light coral and notes that, coming from shallow water, it prefers medium to high light. Too much light bleaches it and makes it shrink, so adjust its position by watching the response.
LiveAquaria gives placement as bottom to middle and flow as medium. Too much flow keeps the disc from opening. It spreads by dividing, so leave clearance from neighbouring corals.
Water 24-26C, specific gravity 1.023-1.025 (salinity 33-35 ppt), pH 8.1-8.4, KH 8-12. Iodine, strontium 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 it semi-aggressive. It can overpopulate and blanket the rockwork, so remove unwanted polyps early. Having no skeleton, it is not covered by the CITES coral listings.
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 Hairy Mushroom (Rhodactis Indosinensis) is 24〜26℃. Avoid sudden temperature changes and maintain a stable environment.
Hairy Mushroom (Rhodactis Indosinensis) feeds on: Nutrition from its zooxanthellae, plus plankton and larger food items it captures.. Aim for a balanced diet with appropriate feeding frequency.
