Crisp Pillow Coral

About

Crisp Pillow Coral (Anomastraea irregularis) is a solid, understated coral that earns its place in a reef tank through resilience rather than flash. Colonies grow in flat to submassive forms, sometimes developing a gentle conical profile, with a surface patterned by neat, evenly spaced septa and thin walls that give the whole structure a tidy, almost geometric look. The base coloration runs from bluish-grey to cream, offset by dark brown polyps that are often partly extended during daylight hours. A behavior you don't see as commonly in corals that reserve feeding activity for the night. In the wild, this species turns up in some genuinely challenging spots: turbid water near reef bases and intertidal pools where light, flow, and water clarity can all be inconsistent. That background makes it a more adaptable coral than many of its relatives, though it still needs decent light and moderate flow to thrive in captivity. Care sits at an intermediate level, so it's probably not the right starting point for a brand-new reef keeper, but hobbyists with a few months of stable tank management under their belt should find it reasonably forgiving. It's a reef-safe species that minds its own business and rewards attentive husbandry with steady, healthy growth.
