Fimbriaphyllia, a euphyllia. Beginner to keep, Typical PAR 75–150, low to moderate flow.
Rarity tier: common, reviewed 2026-08.
A hammer in neon green, named for the flattened anchor or T shape at the tip of every tentacle, which is what tells a hammer from a torch's flowing points or a frogspawn's forked ones.
The colour name is the least useful thing in the listing. What decides the coral is the skeleton under it, and the two forms are sold under the same name: a branching hammer carries each head on its own branch, so a head that goes bad can be cut away and the colony lives on, while a wall hammer shares one continuous skeleton and a problem travels along it. Ask which one it is, or look at the base of the frag for separate stalks against a solid ridge. Then leave it room. Hammers throw sweeper tentacles several inches beyond the polyps and will sting whatever they reach, though they generally tolerate other Euphyllia.
Space to sweep, because the tentacles reach further than they look. Toxic Green Hammer is beginner to keep at a typical PAR of 75–150 in low to 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 head and reported as a median, with what shops ask kept separate from what buyers paid. One head is one polyp of a branching LPS. A five-head piece is divided by five before it is compared to anything. 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.
