Life cycle and mating behavior
Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas
In captivity, as the sperm are released the female sinks to the bottoms, resting on one of her pectoral fins while she starts fanning with the other pectoral fin. At this time, some eggs are released which fall into the pelvic fin basket and are apparently fertilized at that time.
