Turbinaria stellulata
A Turbinaria that grows encrusting to low domes and seldom forms upright plates. Thick-walled conical corallites about 2.5 mm across stud the surface, with the coenosteum darker than the walls. Unlike its relatives, it avoids turbid water.
Turbinaria stellulata is a stony coral of the family Dendrophylliidae ranging from the Red Sea and Madagascar to tropical Australia, southern Japan and the South China Sea. Colonies are mainly encrusting, often forming domes with encrusting margins about 50 cm across. The corallites are thick-walled cones averaging 2.5 mm across. It is usually brown or green but may take other colours depending on its symbionts, and the coenosteum between corallites is usually darker than the corallite walls (Corals of the World, Wikipedia). It lives on upper reef slopes at 2-15 m and, unlike other Turbinaria, seems to avoid turbid water. Turbinaria corallites are immersed almost to the top in the skeleton, and colonies are thick and plate-like (Nipponica). On this site, T. reniformis forms tiers of plates in turbid water and Duncanopsammia peltata has much larger corallites, 5-10 mm across. Specialist shops in Japan stock it by name.

Domestic law: Collecting in Japanese waters is governed by each prefecture's fisheries adjustment regulations, which differ by prefecture. Okinawa bans all collection of reef-building corals, including stony corals, and also bans possessing or selling illegally collected corals (cultured corals are exempt, and the prefecture advises buyers to confirm a coral is cultured, on an artificial base or tagged). Tokyo bans collection in the waters off Ogasawara Village. In marine park zones of national and quasi-national parks, taking designated animals and plants requires a permit (Natural Parks Act, Art. 22).
All stony corals (Scleractinia) are listed in CITES Appendix II (checked on Species+). International trade requires export permits, but no registration is needed to sell or transfer specimens within Japan.

Temperature
24〜27℃
Photosynthesis (zooxanthellae) plus plankton
It hosts zooxanthellae and lives on upper reef slopes, avoiding turbid water (Wikipedia). Give clear water and moderate or brighter light.
It spreads as a crust and grows into a dome, so attach it to a flat rock and give moderate flow that keeps the surface clean.
24-27°C, salinity 33-35 ppt (SG 1.023-1.025); Reeflex gives 24-29°C.
It extends its polyps to feed, mostly at night (Wikipedia). Offer fine particulate or plankton-type food after lights-out.
Moderately easy (Reeflex). Small colonies resemble T. radicalis (Corals of the World), so also check corallite size and shape.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The ideal temperature for Encrusting Turbinaria is 24〜27℃. Avoid sudden temperature changes and maintain a stable environment.
Encrusting Turbinaria typically reaches Dome-shaped colonies about 50 cm across (Wikipedia) as an adult. Size may vary depending on care conditions and individual genetics.
Encrusting Turbinaria feeds on: Photosynthesis (zooxanthellae) plus plankton. Aim for a balanced diet with appropriate feeding frequency.
