The males compete for the attention of the females as they dance and change into brilliant colors
Finally they pair off. The male passes a sperm packet to the female. The eggs are fertilized then deposited into substrate which is poisonous to most marine creatures
From the first moment they emerge from the egg, they are able to change color. Even though swimming is much more difficult for them.
