mouthbreeder, any fish that breeds its young in the mouth. Examples include certain catfishes, cichlids, and cardinal fishes. The male of the sea catfish Galeichthys felis places up to 50 fertilized eggs in its mouth and retains them until they are hatched and the young are two or more weeks old.

What is it called when fish lay eggs?
“The reproductive behaviour of fishes is remarkably diversified: they may be oviparous (lay eggs), ovoviparous (retain the eggs in the body until they hatch), or viviparous (have a direct tissue connection with the developing embryos and give birth to live young).
