Tricolor Anthias

Three colors blending across one small body sounds like overkill until you remember anthias spend their whole lives auditioning for harem status — brighter, bolder patterns tend to win out in the size-and-color hierarchy that decides which female eventually transitions to male. Constant motion in the upper water column and genuinely striking color make the Tricolor one of the more eye-catching anthias in the trade.
