Pachyseris speciosa
A plating stony coral whose surface carries dense, concentric ridges. The corallites lie sunk between them, so no polyps are visible to the eye. It adapts to low and moderate light as well.
Pachyseris speciosa is a reef-building stony coral of the Indo-Pacific, placed by WoRMS in the family Pachyseridae. SeaLifeBase gives its depth range as 4-35 m, and it grows on the deeper parts of reef slopes and under shaded overhangs. Colonies spread as horizontal plates whose surfaces carry dense, concentric ridges. The corallites lie sunk between the ridges, so no polyps are visible to the naked eye. That texture gives it the English name serpent coral, and it is also traded as elephant skin coral. Colour is brown or greyish brown with the ridges standing out lighter. It is zooxanthellate and draws most of its nutrition from photosynthesis. Because it also grows in deeper water it does not require intense light and will keep well under moderate lighting, which makes it comparatively easy. Detritus settling on the upper plate causes tissue recession, so give it strong flow. The IUCN assessed it as Least Concern in 2023, and as a scleractinian it is listed on CITES Appendix II.

Growing anywhere from 4 to 35 m, it does not require intense light. LiveAquaria lists high lighting, but it also keeps well under moderate illumination.
LiveAquaria lists strong flow and a middle position. Detritus settling on the upper plate causes tissue recession, so direct flow to sweep the surface.
Water 24-27C, specific gravity 1.023-1.025 (33-35 ppt), KH 8-12, calcium 400-450 ppm, magnesium 1280-1350 ppm. Sudden swings in alkalinity are the most common cause of tissue recession.
It has no polyps visible to the eye, so target-feeding pellets is not appropriate. Most of its nutrition comes from photosynthesis; liquid or powdered coral foods can be offered as a supplement.
The Japanese name given here properly belongs to the genus Pavona, not to this species. The IUCN lists it as Least Concern, but as a scleractinian it still falls under the blanket CITES Appendix II listing.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The ideal temperature for Pachyseris Speciosa is 24〜27℃. Avoid sudden temperature changes and maintain a stable environment.
Pachyseris Speciosa feeds on: Mainly nutrition from symbiotic zooxanthellae, supplemented with liquid or powdered coral foods.. Aim for a balanced diet with appropriate feeding frequency.
