Short description Morfología | Morfometría

Espinas dorsales (total): 11; Radios blandos dorsales (total): 15-16; Espinas anales 3; Radios blandos anales: 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 Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva

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).
