Leptoria phrygia
A merulinid reef coral whose skeleton is cut by narrow, regularly meandering valleys. Called the least valley coral in English, its evenly spaced valleys and walls give it a fingerprint-like pattern.
Leptoria phrygia is a reef-building merulinid coral; WoRMS gives the Japanese name nagaresango, and in English it is the least valley coral or simply a brain coral. The distribution records held by WoRMS run from the Red Sea, East Africa, Kenya, Madagascar, Mauritius, Reunion, the Seychelles, the Maldives and Chagos to Malaysia, Indonesia and Australia. Colonies grow as hemispheres, domes or encrusting sheets, and the skeleton is cut by narrow, regularly meandering valleys. The valleys and walls are evenly spaced and the septal teeth are uniform, giving the surface a neat fingerprint-like pattern that separates this coral from Platygyra. Colonies are usually brown or green, sometimes with valleys and walls differently coloured. It is stable under moderate light and moderate flow, but its night-time sweeper tentacles are aggressive. As a scleractinian it is on CITES Appendix II.

LiveAquaria gives moderate lighting for brain corals of this type. Reduce the light at first and raise it to the target position over several weeks.
Medium flow, randomised, because detritus settles readily in the narrow valleys. Leave enough space that its sweeper tentacles cannot reach a neighbouring coral.
Water 24-26C, specific gravity 1.023-1.025, salinity 33-35 ppt, KH 8-12. It consumes calcium and magnesium, so test and replenish them regularly.
Most of its nutrition comes from its zooxanthellae. The valleys are narrow, so feed only small amounts of fine particulate coral food after lights-out.
It is told from Platygyra by the narrower, more uniform valleys and walls, which is hard to judge on a living colony. As a scleractinian it is on CITES Appendix II and international trade requires permits.
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 Leptoria is 24〜27℃. Avoid sudden temperature changes and maintain a stable environment.
Leptoria feeds on: Mainly nutrition from symbiotic zooxanthellae, supplemented with fine particulate coral foods offered at night.. Aim for a balanced diet with appropriate feeding frequency.
