Description
A deep-bodied, oval Caribbean surgeonfish that matures from a bright lemon-yellow juvenile into a powder-to-royal blue adult with fine horizontal blue lines and a yellow-edged scalpel on the caudal peduncle. It is a constantly grazing, open-water swimmer that ignores corals and ornamental invertebrates but will bully other tangs and similarly shaped fish, so it should be the only surgeonfish in most systems. Give it a six-foot tank with strong flow, high oxygen, plenty of open swimming lanes and rock for grazing, and feed dried algae daily; it is ich-prone and should always be quarantined.
