Pectinia lactuca
A merulinid reef coral that raises thin, ruffled plates ending in sharp points. Called the lettuce or carnation coral in English, it is usually green or brown and darkens towards the centre. It is demanding in the aquarium.
Pectinia lactuca is a reef-building merulinid coral known in English as the lettuce, carnation or cabbage coral. The distribution records held by WoRMS cover East Africa, Kenya, Madagascar, Aldabra, the Maldives, India, Reunion, the Ashmore and Cartier Islands and Australia. Colonies raise thin, ruffled plates that end in sharp points, giving the look of cabbage or lettuce leaves. Colour ranges through green, brown and bluish shades, usually darkening towards the centre of the colony. LiveAquaria rates the genus as difficult to keep: tissue recedes quickly after sudden changes in water chemistry or a rise in nutrients, so it suits tanks that can hold a stable environment for a long time. The thin, sharp plate margins also need careful handling. As a scleractinian it is on CITES Appendix II.

LiveAquaria gives moderate lighting for Pectinia. Strong light makes the tissue retract, so place it from mid-height downwards and start at an even lower intensity.
Medium flow, randomised, because detritus collects between the plates. The plate edges are sharp and will injure neighbouring corals, so leave generous space.
Water 24-26C, specific gravity 1.023-1.025, salinity 33-35 ppt, KH 8-12. It is intolerant of sudden swings and rising nutrients, so stability matters more than anything else.
Most of its nutrition comes from its zooxanthellae. Feed small amounts of fine to small particulate coral food after lights-out; overfeeding raises nutrients and triggers tissue recession.
LiveAquaria rates the genus as difficult. The thin, sharp plates chip easily, and tissue can recede from a broken edge. As a scleractinian it is 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 Pectinia Lactuca (Lettuce Coral) is 24〜27℃. Avoid sudden temperature changes and maintain a stable environment.
Pectinia Lactuca (Lettuce Coral) feeds on: Mainly nutrition from symbiotic zooxanthellae, supplemented with fine to small particulate coral foods offered at night.. Aim for a balanced diet with appropriate feeding frequency.
