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
بلوغ | تولید مثل | تخم ریزی | تخم ها | Fecundity | توزاد ( لارو)
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).
