Morphology | Morphometrics
Preopercle smooth, scales smooth, no scales on midline in front of dorsal fin.
Prefers clear insular waters of oceanic islands (Ref. 9626). Has a commensal relationship with the conch shell Lobatus gigas (where it is found in the mantle cavity) and with the bivalve Atrina rigida (Ref. 9626). Emerges at night from the conch shell to feed on small crustaceans. Males brood the eggs in their mouths. (Ref. 26938).
