Caryophyllia quadragenaria

About

Caryophyllia quadragenaria is a solitary stony coral belonging to the Caryophylliidae family, found across the Indo-West Pacific including waters within the New Zealand Exclusive Economic Zone. Like other members of this genus, it forms a single small cup-shaped corallite rather than building the branching or massive colonies more commonly seen in reef aquariums. In the wild it tends to occupy deeper, cooler, and often dimly lit environments, which shapes its aquarium requirements considerably compared to the high-light, high-flow corals that dominate most reef setups. Under aquarium conditions, moderate lighting and moderate water movement appear to suit it well, and its care is rated at an intermediate level, meaning some prior experience with reef systems will serve you well before taking one on. This is not a coral you keep for bold colony growth or dramatic spread across your rockwork. Instead it rewards patient keepers who appreciate the understated geometry of a single polyp and the challenge of replicating the lower-energy conditions it prefers. Documentation on this specific species in the hobby is limited, so networking with other keepers who have direct experience with Caryophyllia species is worthwhile before acquiring one.
