Taille / Poids / Âge
Maturité: Lm ?  range ? - ? cm
Max length : 10.0 cm TL mâle / non sexé; (Ref. 7251)
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).
Body shape (shape guide): elongated.
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). Monogamous and always in home-ranging pairs, that is they do not defend an exclusive territory (Ref. 52884). Has been reared in captivity (Ref. 35427).

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).
