Temperature
24〜27℃
Diet
Mainly nutrition from symbiotic zooxanthellae, supplemented with powdered or liquid coral foods and phytoplankton.
About
Acropora horrida was described by James Dwight Dana in 1846. It occurs in the Red Sea, the Indian Ocean, the Gulf of Aden, the Persian Gulf, the Indo-Pacific, the East China Sea, Japan, Southeast Asia, the Line Islands, Indonesia and Palau; its range is wide but it is not common. It lives mainly in turbid water near fringing reefs, and also in shallow lagoons and on sand slopes, at depths of 5-20 m. Colonies are mainly open-branched: in turbid water the branchlets are unstructured, while in clear water they are short, giving the colony a bristly look. The corallites are rough and irregularly placed, and the tentacles enlarge during the day. Colour is light blue, dark blue, light yellow or brown, with white or pale blue polyps. It is believed to live more than ten years and to reach maturity between three and eight. The IUCN assessed it as Endangered in 2023 and it is listed on CITES Appendix II.

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 Prefecture's regulations ban the collection of reef-building corals, including stony corals (Scleractinia), organ-pipe corals (Tubiporidae) and blue coral (Helioporacea); this covers corals naturally attached to quays or ropes, broken fragments lying on the seabed, and skeletons. Possessing or selling illegally collected corals is also banned. Cultured corals are exempt, and the prefecture advises buyers to confirm that a coral is cultured, on an artificial base or tagged.
