Egg time

Eggs of all kinds of species cover every conceivable surface of the reef. Male clown fish and damselfish guard theirs. A pair of cuttlefish court and the male chases off a rival. He then guards the female while she lays her eggs to ensure he is the one to fertilise them. The eggs have been carefully cemented on to the walls of a crevice, where they'll be safe until they hatch.
