Description

A small, cave-dwelling plesiopid with a deep blue to blackish-blue body, fine dark speckling, and bright blue-edged fins that develop reddish accents with maturity. It is shy and cryptic on introduction, hovering and often swimming upside down beneath overhangs and in caves, and is peaceful toward tankmates though territorial with conspecifics, keep one per tank unless it is a bonded pair or a large system. Provide a mature reef with abundant rockwork, caves and overhangs, moderate flow, calm tankmates, and a tight-fitting lid, and offer small meaty foods several times a week.
