Tiger Cardinalfish

Cheilodipterus macrodon


Cardinal Fishes are known to be mouth brooders, meaning the males of the species carries eggs in their mouth and will spit out and swallow back the eggs from time to time to aerate it. During this time, they do not feeds, and may at time, consume some of the eggs they are brooding. After the female lays her eggs on the sea bottom, the male will fertilise them before picking them up and keep them in his mouth.

@Sukanya - they looks scare but harmless, to divers/humans.
This fish is just around 15 cm in size.
