Life Cycle
In nuptial colours the male develops a deep red throat.

Lays eggs which hatch larvae, that pass through many developmental stages before maturity. Eggs laid in groups hidden away in nests in cracks and holes, and fertilized by the males. Males actively protect the nest, by keeping away predators. Males also fan the eggs as they hatch to produce the larvae. The larva hatches it goes off on its own; before developmental stages of the pre-transitional stage followed by the transitional stage, and finally the juvenile stage.
