The male builds a nest out of air bubbles on the surface of the water and then entices the female to lay her eggs under it, wrapping his body around hers to fertilize the eggs as she lays them.
He then collects the eggs into his mouth and places them into his bubble nest. After breeding, the male chases the female away and takes care of the eggs and the babies. The female must be removed or she will be attacked by the male. Generally speaking, catfish sexes cannot be distinguished. Many species of catfish have not been breed in captivity.
The notable exception is the Corydoras specieswhich has often been breed in captivity. In the Corydoras catfish, the female is usually a bigger-bodied fish than the males. The males will chase a gravid female full of eggs around the tank and then she will lay the eggs on a flat surface, such as a plant leaf, smooth rock, or even the aquarium glass. The males swim over the eggs and fertilize them, then the eggs are abandoned. Cichlids are such a diverse group that it would take a small novel to give specifics for knowing the difference within each species.
While many are not easily differentiated, there are a few rules of thumb that apply to quite a few cichlid species. Males are often slimmer but larger-bodied than females and are more vibrantly colored.
The dorsal and anal fins of the male are more pointed, larger and more flowing than in the female. In many species, the male will display egg-shaped markings on the anal fin known as egg spots. Some males have a bump on the head, referred to as a nuchal hump. Although females can also develop a nuchal hump when spawning, it is never as prominent as that of the male. Typically the dominant male will have a larger nuchal hump than other males. Although the above general rules apply to many species of cichlids, if you are considering breeding them, do your homework on the specific species before seeking a breeding pair.
