Zoanthus, a zoanthid. Beginner to keep, Typical PAR 75–150, moderate flow.
Also sold as RDE.
Rarity tier: common, reviewed 2026-08.
A green-centred zoa: the face is the intense green the name is about, and the skirt runs green to yellow-green around it. The face is the brightest part of the polyp, not the darkest.
This entry used to have the colours the wrong way round, and the mistake is the one the market makes too. Plain Dragon Eye is the orange-faced coral, an orange centre inside a blue ring inside a bright yellow skirt, and it is the cheaper animal that gets sold under the radioactive name. So the question at the counter is simply which colour the face is: green is the one you are paying for, orange is the one you are not. Both are easy, both multiply readily, and neither is scarce enough to justify a stretch on a blurry photograph.
Low to middle rock, enough flow to keep detritus off the mat. Radioactive Dragon Eye is beginner to keep at a typical PAR of 75–150 in moderate flow. A typical starting range for this type of coral rather than a measured requirement for this morph. Spectrum, how it was acclimated and the system it grew in all move it.
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. Shops are typically asking $7 to $9 per polyp, median $7, across 3 shops surveyed on 2026-09-07; the full sweep ran $6 to $10. Asking prices are what sellers want, not what buyers paid.
