Acropora solitaryensis
An Acropora described by Veron and Wallace in 1984. It occupies a broad depth band of 2-30 m and in subtropical locations also occurs on rocky foreshores. Its Japanese name is simply midoriishi.
Acropora solitaryensis was described by Veron and Wallace in 1984. SeaLifeBase records it as reef-associated at depths of 2-30 m across the Indo-Pacific, between 35N and 30S and from 95E to 175W. Reaching 35N makes it one of the higher-latitude members of the genus, and in subtropical locations it is indeed found on rocky foreshores as well as on subtidal reef slopes, walls and submerged reefs. WoRMS gives its Japanese name as midoriishi, the same word used for the genus as a whole, so it is safer to cite the scientific name alongside it. Husbandry requirements are those of the genus: strong light, strong flow and a stable supply of alkalinity and calcium. The IUCN assessed it as Endangered in 2023 and it is listed on CITES Appendix II.

Origin
Indo-Pacific, between 35N and 30S and from 95E to 175W
Temperature
22〜26℃
Mainly nutrition from symbiotic zooxanthellae, supplemented with powdered or liquid coral foods and phytoplankton.
Requires strong light. AlgaeBarn cites successful Acropora keeping at PAR 800 or more. Start newly added colonies under reduced light and raise it over several weeks.

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.

It lives on subtidal reef slopes, walls and submerged reefs across a broad 2-30 m range. In the aquarium give it the strong randomised flow typical of the genus.
Water 22-26C, specific gravity 1.023-1.025, KH 8-12, calcium 380-440 ppm, magnesium 1300-1400 ppm. Sudden swings in alkalinity are the most common cause of tissue loss.
Most of its nutrition comes from photosynthesis by its zooxanthellae. Powdered or liquid coral foods and phytoplankton can be offered as a supplement, but stable light and water chemistry matter more than feeding.
A higher-latitude species reaching 35N. Its Japanese name is also the general term for the whole genus Acropora, so stock offered under that name alone may be a different species; check it against the scientific name Acropora solitaryensis. Listed on CITES Appendix II.
Advanced. This is an advanced-level species. It requires specialized equipment and advanced husbandry skills with precise environmental control.
The ideal temperature for Acropora Solitaryensis is 22〜26℃. Avoid sudden temperature changes and maintain a stable environment.
Acropora Solitaryensis feeds on: Mainly nutrition from symbiotic zooxanthellae, supplemented with powdered or liquid coral foods and phytoplankton.. Aim for a balanced diet with appropriate feeding frequency.
