Overview

Palythoa grandis (family Sphenopidae) is a colonial hexacoral (a button-polyp/zoanthid relative) distributed across Atlantic and Caribbean reefs, bearing especially large polyps for the genus. Large polyps several centimeters across cluster together, showing greens, browns, and golds. It is relatively easy to keep, tolerating moderate lighting and gentle to moderate flow. Feeding is optional, though the thick polyps may capture small seafood pieces. Because Palythoa can contain the potent toxin palytoxin, never handle it with bare hands, wash thoroughly afterward, and never boil or use hot water on it—strict safety precautions are essential. It can be propagated by fragging, but toxin precautions during handling are especially important for this species.
