🥚 Reproduction

🐣 Oviparous 👄 Mouth Brooder
Spawning Season
spring
Spawn Location
Substrate
Fertilization
External

Ovigerous female develops large pads on the inner side of the last ventral fin rays. As the few but large eggs are extruded, the pads serve to hold the eggs until they can be fertilized and taken into the mouth by the male. Male then incubates the eggs until hatching and continues to protect the fry in his mouth until the yolk sacs are completely absorbed.
