About
Acropora nana is an SPS coral of the family Acroporidae distributed on reefs from the western Indian Ocean to the central Pacific. Colonies are compact clumps of long, straight, non-tapering branchlets radiating at equal spacing from a solid base. Axial corallites are tubular and radial corallites are long, tubular and appressed. Colour is cream, blue or purple, usually with purple branch tips, and the whole colony is delicate, with branchlets that break apart readily (Corals of the World). It lives on outer reef flats with strong currents or wave action. Acropora valida can look very similar in wave-washed habitats but has thicker branchlets and chunkier radial corallites. It is listed as Endangered on the IUCN Red List. In the aquarium it is a coral for experienced SPS keepers, needing strong light, brisk flow and very stable water. In Japan it is offered by name through large online retailers.

Regulations & Conservation Status
CITES Appendix IIIUCN EN · Endangered
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.
