Care notes
A dark morph: a near-black face with sparse orange specks and an olive-yellow glow at the center, ringed by dark tentacles flecked with orange, red and yellow. Under strong blue light the colors look more intense, and under whiter light they look softer. Care values here are typical for zoanthids, not measured for this morph: medium light, moderate, indirect flow and steady water. Give a new frag time to settle before judging its growth or color, and if it starts to pale, move it lower rather than changing several things at once. Zoa trade names are used loosely, and colonies sold under this name can look different, so buy from photos of the actual colony.
⚠ Palytoxin safety
Like any zoanthid, CK Antimatter may contain palytoxin, so treat it as toxic. Wear gloves and eye protection when handling or fragging, and wash up afterward.
