Acropora millepora. Expert to keep, Typical PAR 200–350, high flow.
Rarity tier: ultra, reviewed 2026-08.
A. millepora carrying several strong pigments at once, commonly red or purple corallite rims over green branch stems with contrasting polyps. Millepora is the species with the widest colour range in the genus, which is why the name exists and why no single colourway defines it; the reliable tell is the animal's shape, not its palette. Thick clustered branches and unusually long polyp extension give it a distinctly fuzzy outline even from across a tank.
'Rainbow' is applied loosely. Two clearly distinct colours in the same photo under white light is the minimum bar. Judge the fuzz and the branch structure first: those hold when the colour does not.
High light and strong random flow, up in the rockwork. Rainbow Millepora is expert to keep at a typical PAR of 200–350 in high 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 frag and reported as a median, with what shops ask kept separate from what buyers paid. One frag is a single cut on a plug, whatever its exact size. Colonies, mini colonies and mother stock are excluded rather than averaged in. Nothing on this page is for sale. The survey found it at 1 of the 107 shops read on 2026-09-07. A range publishes from 3 shops up, so 2 more would have to list it before a figure appears here. One shop's asking price is that shop's opinion rather than a market.
