Leptastrea purpurea
An encrusting stony coral that spreads as a thin sheet over rock. Known in English as the crust coral, it usually shows contrasting colour in the centre of each corallite, and the orange-eye colour form is well known in the trade.
Leptastrea purpurea, the crust coral, is an encrusting stony coral in the family Leptastreidae. The distribution records held by WoRMS run from the Red Sea, East Africa, Kenya, Madagascar, the Maldives and Chagos to Indonesia, the Philippines, Papua New Guinea, the Marshall Islands, American Samoa and Midway Atoll, covering much of the Indo-Pacific. Colonies spread as a thin sheet over rock and live rock, with nearly circular corallites packed against one another. The centre of each corallite is often a contrasting colour, and specimens with bright orange or red oral discs are traded as orange-eye Leptastrea. It grows well under moderate light and moderate flow, but it is aggressive and will digest the tissue of anything it touches to take the substrate. Growth is steady and encrusting, filling gaps in the rockwork. As a scleractinian it is on CITES Appendix II.

Mainly nutrition from symbiotic zooxanthellae, supplemented with fine particulate coral foods offered at night.
LiveAquaria gives moderate lighting for Leptastrea. Too much light washes out the oral-disc colour, so place it from mid-height downwards and adjust while watching the colour.
Medium flow. Placement from the sand bed to mid-height is fine, but it encrusts outwards and will overgrow neighbours, so mount it on its own rock or where it has room.
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 corallites are small, so feed only small amounts of fine particulate coral food after lights-out.
LiveAquaria classes the genus as aggressive; it digests the tissue of anything it touches, so keep it apart from other corals. As a scleractinian it is on CITES Appendix II and international trade requires permits.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The ideal temperature for Leptastrea is 24〜27℃. Avoid sudden temperature changes and maintain a stable environment.
Leptastrea typically reaches Encrusting colonies to around 10-20 cm across as an adult. Size may vary depending on care conditions and individual genetics.
Leptastrea 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.
