Platygyra daedalea
A merulinid reef coral whose skeleton is cut by maze-like valleys. Known as the lesser valley coral, it forms colonies that can exceed a metre across and is very common on shallow Indo-Pacific reefs.
Platygyra daedalea, the lesser valley coral, is a merulinid reef coral widespread on shallow Indo-Pacific reefs. Colonies usually form domes or boulders more than a metre across, and can also be plate-like or encrusting. The polyps sit in meandering valleys separated by low walls, with a raised columella visible along the centre of each valley. Its range runs from Madagascar, the East African coast, the Red Sea and the Gulf of Aden to Australia, Indonesia, Japan and the South China Sea, and it is most abundant on back reef slopes from subtidal rock down to about 30 m. The polyps expand at night to take zooplankton, but most of the coral's nutrition comes from photosynthesis by its zooxanthellae. Against competing corals it deploys sweeper tentacles up to 90 mm long, about fifteen times the length of an ordinary tentacle. The IUCN rates it Least Concern, and as a scleractinian it is on CITES Appendix II.

Mainly nutrition from symbiotic zooxanthellae, supplemented by zooplankton caught with the tentacles at night.
LiveAquaria gives moderate lighting for Platygyra. It is a shallow-water coral, but a sudden move into strong light will bleach it, so acclimate over several weeks.
Medium flow, randomised so detritus does not settle in the valleys. It extends sweeper tentacles up to 90 mm long, so leave at least 10 cm between it and its neighbours.
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.
It expands its polyps at night to take zooplankton. Most of its nutrition is from its zooxanthellae, but meaty coral food after lights-out speeds growth.
It is highly aggressive, and in experiments destroyed the tissue of another coral in the same family. WoRMS treats the name as an unreplaced junior homonym, so the scientific name may change. As a scleractinian it is on CITES Appendix II.
Beginner. This is a beginner-friendly species. No special equipment or experience is required, and it can be kept successfully with basic care setup.
The ideal temperature for Platygyra Daedalea is 24〜27℃. Avoid sudden temperature changes and maintain a stable environment.
