 Inhabit seaward reefs in areas with rich coral growth. Usually solitary, but also a schooling species that is often on the move, usually in areas prone to strong currents. Usually deep in Indonesia and adults are rarely found in less than 40 m depth. Mainly found in sponge zones and deep water occurrence is habitat related, not cold water as sometimes suggested. This species will travel in open water and cleans large pelagic fishes (Ref. 48636). Oviparous (Ref. 205). Form pairs during breeding (Ref. 205).

 Preferred temperature (Ref. 
115969): 19.9 - 28.9, mean 27.4 (based on 356 cells). 
 
 
 
 Phylogenetic diversity index (Ref. 
82805):  PD
50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. 
 Bayesian length-weight: a=0.02291 (0.01113 - 0.04716), b=3.01 (2.84 - 3.18), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref.
