Sun Coral
Tubastraea chloromura
A rare subtropical sun coral from Hong Kong's reefs, thriving in low light.
About
Found on shallow subtropical reefs off Hong Kong, Tubastraea chloromura is one of the lesser-known members of the sun coral group, a genus recognized for its bold, non-photosynthetic polyps that depend entirely on direct feeding rather than zooxanthellae. This species has been recorded at depths down to around 10 meters in reef-associated habitats across the Northwest Pacific, making it a genuinely uncommon find both in the wild and in the hobby. Like its relatives, it does well under low light conditions, which sets it apart from the majority of corals that demand intense illumination. That same trait makes placement more flexible in a reef system, though keepers should not mistake low light tolerance for low maintenance. Regular target feeding is essential to keep the colony healthy and expanding. Moderate flow helps deliver food to the polyps and keeps detritus from settling on the colony. Because consistent feeding is non-negotiable and the species is not especially common in the trade, it sits comfortably in the intermediate care category. Hobbyists already experienced with other Tubastraea species will find the husbandry approach familiar, though published data on this particular species remains limited.
