Representative Rock flower anemonephoto — a dedicated image of this exact morph isn't available yet.

The classic deep rose-to-maroon bubble-tip anemone (*Entacmaea quadricolor*), the long-standing hobby favorite that predates the fancier sunburst strains. Bubble-tipped tentacles in solid rose-red.

📜 Backstory

Rose bubble-tips have been traded by hobbyists for decades and are the most widely propagated colored *Entacmaea*; the Colorado Sunburst is genetically the same species, just a different color strain. Sold widely (LiveAquaria, Aqua Imports, Vivid Aquariums and many farms), usually aquacultured. Listed as the baseline named BTA; a bubble-tip rather than a true rock flower.

Keeper tips for this variant

A hardy, relatively beginner-friendly BTA that hosts clownfish; give it rock to climb, good light, and a guarded powerhead, then let it pick its own home.
