				Adults inhabit silty lagoon and coastal reefs around coral outcrops and seagrass beds (Ref. 9710).  Often adjacent to clear mangrove coasts among rubble and Sargassum algae, to a few meters depth (Ref. 48636).  Oviparous, distinct pairing during breeding (Ref. 205).  Eggs are demersal and adhere to the substrate (Ref. 205).  Males guard and aerate the eggs (Ref. 205). Diurnal species (Ref. 52881).

					Estimates based on models				
				
				
				Preferred temperature (Ref. 
123201): 27.6 - 29.3, mean 28.8 °C (based on 1291 cells).
				
				
					
					Phylogenetic diversity index  (Ref. 
82804):  PD
50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].					
													Bayesian length-weight: a=0.01479 (0.00651 - 0.03363), b=3.00 (2.81 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 
93245).
					
					Trophic level  (Ref. 
69278):  2.0   ±0.00 se; based on food items.					
											
				
				
										
						Resilience  (Ref. 
120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).					
											
				
									
					Fishing Vulnerability  (Ref.
