Zoanthus, a zoanthid. Beginner to keep, typical PAR 75–150, moderate flow.
Also sold as Rainbow Hornets, Rainbow Hornet Zoanthids.
A loose trade name. Sellers use it loosely, so trust the photo over the label.
Collector tier: uncommon, reviewed 2026-08.
A zoa with an orange skirt, a blue to deep purple face, and a thin bright yellow ring tight around the mouth. The mouth itself is called silver, white or blue, depending on the shop, and whether the skirt is banded is disputed: one source says it alternates, another that it does not.
The yellow ring around the mouth is the one thing every description agrees on; face colour splits between blue and purple, which blue light blurs anyway. A Fire and Ice is also blue with an orange skirt, but has a pale centre and no yellow ring. A Red Hornet carries its ring in red, and a Blue Hornet has no orange at all. Several farms grow their own, and early listings point to Cherry Corals, though no one is named as the originator.
Low to middle rock, enough flow to keep detritus off the mat. Rainbow Hornet is beginner to keep at a typical PAR of 75–150 in moderate flow. A typical starting range for this type of coral, not measured on this one.
No verified sales yet. A range publishes once 3 dated, checkable records from 3 different sources exist, priced per polyp and reported as a median, with what shops ask kept separate from what buyers paid. One polyp, so a ten-polyp frag is divided by ten. Listings that do not state the count are dropped rather than assumed. Nothing on this page is for sale.
