A Zoanthid relative with large button-like polyps growing densely. Hardy with rich colors.
Palythoa (family Palythoidae) is a genus of colonial hexacorals closely related to Zoanthus, distributed across tropical and subtropical reefs of the Indo-Pacific and Atlantic. Large polyps 1–3 cm in diameter incorporate sand grains and detritus into thick, rubbery mats, giving colonies a chunkier appearance than Zoanthus. Colors range from earthy browns and greens to brilliant blues and purples, with fluorescent morphs highly valued by collectors. Care is exceptionally easy; Palythoa adapts to a wide range of lighting (50–250 PAR) and flow conditions. Critically, Palythoa may contain palytoxin, one of the most potent biological toxins known—bare-hand contact must be avoided at all times. Fragging is simple, and large colonies can be divided rock-and-all. An ideal coral for beginners despite the handling precaution.

It adapts to a wide range of light (50-250 PAR). It is not fussy about placement and can be kept at any level of the tank.
It adapts to a broad range of low to moderate flow. It spreads as a thick encrusting mat, so place it on rock with room to expand.
Maintain 24-27C, KH 8-11 and specific gravity 1.025. It is very hardy and grows in the water quality of an ordinary marine tank.
It is easy to divide by fragging, and a large colony can be split rock and all. As a palytoxin precaution, never handle it bare-handed and wash your hands thoroughly afterward.
Some contain palytoxin, handle with care
