A variant of Rock flower anemone (Phymanthus crucifer)
Representative Rock flower anemonephoto — a dedicated image of this exact morph isn't available yet.
A bubble-tip anemone (*Entacmaea quadricolor*) showing a subtle blend of orange, green, red, purple and blue across its tentacles. The multi-color expression is what earns the "rainbow" grade.
📜 Backstory
Sold by Tidal Gardens, Whitlyn Aquatics, Unique Corals and many aquaculture facilities as "Rainbow" or "Rainbow Rose" BTAs; coloration intensifies under proper lighting. These are wild-derived color forms that are then split and propagated, so individual lineage is often debated. A bubble-tip, distinct from *Phymanthus* rock flowers.
Keeper tips for this variant
Aim for solid PAR (these color up best with good light) and a stable, mature tank; give it a rocky spot and keep flow moderate so tentacles bubble properly.
