Psammocora spp.
A genus of stony corals whose surface has a fine, sand-grain texture. The corallites are extremely small, and colonies may be encrusting, columnar or foliose depending on the species.
Psammocora is a genus of reef-building stony corals distributed across the tropical and subtropical Indo-Pacific, placed by WoRMS in the family Psammocoridae. The genus name means sandy and refers to the fine, sand-grain texture of the surface. The corallites are about a millimetre across, and their septa run outward as thin ridges, giving the surface a reticulated look. Colony shape varies by species, from encrusting sheets through columns to foliose plates. Colour may be brown, green or purplish brown, with green and purple colonies favoured for aquariums. The genus is zooxanthellate and draws most of its nutrition from photosynthesis. Among small-polyp stony corals it is not a difficult group to keep, staying stable under moderate light and flow. In Japan it is generally traded under the name Samocora. As scleractinians, all species fall under the blanket CITES Appendix II listing.

Stable under moderate light. A sudden jump to very strong light bleaches it, so start at reduced intensity and raise it gradually.
Give moderate randomised flow and place it at mid-height on the rockwork. Encrusting species will grow over neighbours, so leave clearance.
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.
Most of its nutrition comes from photosynthesis by its zooxanthellae. Powdered coral foods and phytoplankton can be offered as a supplement, but stable light and water chemistry matter more than feeding.
This profile covers the genus Psammocora as a whole, and growth form and light requirement differ between species. As scleractinians they fall under the blanket CITES Appendix II listing and trade requires permits.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The ideal temperature for Psammocora is 24〜27℃. Avoid sudden temperature changes and maintain a stable environment.
Psammocora feeds on: Mainly nutrition from symbiotic zooxanthellae, supplemented with powdered coral foods and phytoplankton.. Aim for a balanced diet with appropriate feeding frequency.
