📜 Backstory

Popularized and aquacultured by Eye Catching Coral (ECC) and widely resold by Bulk Reef Supply, Corals.com, Top Shelf Aquatics and Kush Corals. It is one of the most recognizable named BTAs in the hobby. A bubble-tip strain rather than a true rock flower; included as part of the broader named-anemone trade.

Keeper tips for this variant

Provide moderate-to-strong reef light (roughly 150–350 PAR) and let it choose a rock crevice; feed silversides or chopped seafood occasionally to keep the warm colors saturated.
