This species is monogamous: the fish form a pair that remains together for a long time. It is important to note that not every male and female pair is compatible – they are quite selective in their choice. Consequently, the larger the group size, the higher the probability of successful pair formation. At the beginning of the breeding season, the pair retreats to their chosen refuge, be it a cave or grotto, which is then actively defended from both conspecifics and other fish. Inside this shelter, the female lays a small number of eggs, and after their fertilization, she remains near them at the entrance to the cave while the male patrols the surrounding territory. The incubation period lasts 2–3 days, and within a week, the fry begin to move freely. The young may remain under parental care until they reach sexual maturity or until the pair starts a new clutch.
