Care notes

Day-to-day care is simple, but handling it safely is the hard part, which is why it is rated Moderate rather than Easy. It is a true Palythoa, not a zoa sold under a “paly” name, and hobbyists have reported illness after handling it, in at least one case even when wearing gloves. Polyps are fleshy, with a thick mat that can pick up sand. The purple discs and green centers stand out under blue light. It grows fast and readily takes food, so it can take over a rock if left alone. Keep it on its own rock so you never have to cut it back in place. If you aren’t prepared to follow full palytoxin precautions, choose a Zoanthus morph instead.

⚠ Palytoxin safety

Purple Death is a true Palythoa, and hobbyists commonly report illness after handling it. Always wear gloves and eye protection, never frag it out of water or with power tools, and never boil or scrub rock it grows on. See the Palytoxin Safety guide before handling it.
