Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Ovophile mouth brooders. The parent fish clean the rocky substrate prior to spawning. Incubation takes place in the mouth. Juveniles use the mouth as their shelter for several weeks, where they attach themselves to the palate, by means of a specific gland (Ref. 35237).
