A fluorescent-green to lime rock flower anemone (*Phymanthus crucifer*) whose disc and tentacle tips pop hard under blue light. Often paired with a red or orange mouth for contrast.

📜 Backstory

Listed as "Green" or "Ultra Green" rock flower by The Coral Farm, Eastern Shore Corals, LiveAquaria and similar Florida-keys collectors. Like the other color grades, it is wild-harvested and sorted by color, not a man-made strain. Considered one of the more common and affordable rock flower color forms.

Keeper tips for this variant

Give it a spot with a little more blue/actinic light to bring out the green fluorescence, but keep flow gentle so the short tentacles stay fully expanded. Feed small meaty foods weekly.
