Rainbow Acan Bowerbanki Frag (Acanthastrea bowerbanki)

Rainbow Acan Bowerbanki Frag (Acanthastrea bowerbanki) is a fleshy large-polyp brain coral whose inflated tissue and color are best supported by stable reef conditions, modest light, and gentle indirect water movement.

Care and Placement

Fleshy large-polyp brain corals respond best to stable reef conditions. Give the coral a flat, secure position where the tissue can expand without rubbing against sharp rock or being pressed against the skeleton by direct flow. Acclimate gradually to the stated light range.

Keeping the Tissue Healthy

Keep detritus from settling in folds and valleys, but avoid a direct powerhead stream. The coral may inflate beyond the visible skeleton, so allow room for daily expansion and nighttime feeding behavior. Handle the skeleton rather than the living tissue whenever possible.

Consistency matters more than chasing a single number. Make lighting and flow changes gradually, keep alkalinity and salinity steady, and watch tissue inflation as the clearest day-to-day placement signal.
