Pectinia paeonia
A merulinid reef coral whose thin walls rise irregularly and end in sharp points. Called the hibiscus coral in English, its valleys are deeper and more intricate than those of the lettuce coral, and it is demanding to keep.
Pectinia paeonia is a reef-building merulinid coral known in English as the hibiscus coral. The distribution records held by WoRMS cover Chagos, the Ashmore and Cartier Islands, Australia, Papua New Guinea and Fiji, placing it in the tropical Indo-Pacific. The skeleton consists of thin walls that rise irregularly and end in sharp points; compared with the lettuce coral of the same genus, the valleys are deeper and more intricate and the walls tend to radiate outwards. Colonies are usually green or brown, sometimes with paler ridge tips. LiveAquaria rates the genus as difficult: it is intolerant of sudden changes in water chemistry and of rising nutrients, and suits tanks that hold a stable environment under moderate light and moderate flow for long periods. The thin skeleton chips easily, and tissue can recede from a broken edge. 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 in the intricate valleys. The sharp ridges injure neighbouring corals, so leave space around it.
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.
Its skeleton resembles that of the lettuce coral of the same genus and the two are hard to tell apart alive. The thin skeleton chips easily and needs careful handling. As a scleractinian it is on CITES Appendix II and international trade requires permits.
Advanced. This is an advanced-level species. It requires specialized equipment and advanced husbandry skills with precise environmental control.
The ideal temperature for Pectinia Paeonia is 24〜26℃. Avoid sudden temperature changes and maintain a stable environment.
Pectinia Paeonia 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.
