Rainbow BTAs are the most-sought bubble tip anemone color morph. Multiple gradient bands across each tentacle - typically green, purple, orange, and red. Aquacultured Rainbow BTAs trade for $150-400 per anemone, making them one of the most expensive anemone purchases in the hobby.
Rainbow BTAs (Entacmaea quadricolor) are color-morph variants of the standard bubble tip anemone. Signature traits:
Small Rainbow BTA (2-3 inch): $150-250.
Medium (4-6 inch): $250-400.
Large show specimen (8-12 inch): $400-700.
Premium grades (vibrant 4-band specimens) clear $500+. Standard Rose BTA (single-band orange-red) starts around $40 - much cheaper.
Same as standard bubble tip anemone. 100-200 PAR, moderate flow, stable parameters. Full care guide →. Compatibility chart →.
Critical: Rainbow BTAs need stable established systems (6+ months mature) + steady alkalinity. Parameter drift causes color regression. Light acclimation over 2-3 weeks if moving from a different system.
Fast Aquatics aggregates Rainbow BTA listings from charter aquaculture vendors. Verify the source - multi-band coloration takes 6-12 months under stable conditions to fully express. Pictures should show actual specimen under standardized blue + white lighting.

Browse Rainbow BTA listings →Yes if parameters are stable + lighting is appropriate (100-200 PAR with strong blue spectrum). Color regression to standard rose BTA pattern happens with alkalinity drift, light acclimation issues, or move stress.
Yes - BTAs reproduce by binary fission. A healthy Rainbow BTA in optimal conditions can split every 6-12 months, producing two genetically-identical clones. This is how the cultivar propagates.
