Description synthétique Morphologie | Morphométrie

Épines dorsales (Total): 11; Rayons mous dorsaux (Total): 15-16; Épines anales 3; Rayons mous anaux: 14 - 15. Body light bluish gray with numerous pale blue dots; head, nape and anterior part of dorsal fin yellow; a pair of black spots often present on chin (Ref. 13442).

Inhabit burrows made of crushed coral or sand. Hovers vertically, above or near its hole. The male courts the female by swimming in an arched position with his fins spread towards her (Ref. 9710). Male broods the eggs orally (Ref. 5521). Has been reared in captivity (Ref. 35427).

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

Mouthbrooders. Eggs which are clumped together in a sticky ball get incubated inside the male's mouth (Ref. 5521). Monogamous mating is observed irrespective of resource abundance (Ref. 52884).

Estimates based on models

Preferred temperature (Ref. 115969): 24.7 - 28, mean 27 (based on 402 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.0 ±0.1 se; based on diet studies.

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
