Juveniles are encountered under ledges, or in holes of outer lagoon patch reefs or semi-protected areas of exposed channels and outer reef flats. Subadults move to reef front holes and surge channels. Large adults inhabit ledges and caves in areas of rich coral growth on clear lagoon, channel, or seaward reefs (Ref. 6113). Benthopelagic (Ref. 58302). Feed on sponges and other encrusting organisms (Ref. 6113); also on tunicates. Form pairs. Young and adults may clean much larger fishes such as sunfish (Ref. 48636). Frequently exported through the aquarium trade. Juveniles are distinguished by a white dorsal-fin margin (Ref. 48391).

Estimates based on models
Preferred temperature (Ref.
123201): 24.6 - 29, mean 27.9 °C (based on 1496 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02512 (0.01462 - 0.04317), b=2.87 (2.73 - 3.01), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.9 ±0.05 se; based on food items.
Generation time: 16.4 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilienza (Ref.
120179): Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
