The dwarf hawkfish, Cirrhitichthys falco, is a species of hawkfish found on tropical reefs of the Indian Ocean and the western Pacific Ocean. This species can reach a length of 7 centimetres (2.8 in) TL. It can also be found in the aquarium trade.
It is red-pink and white in color, and has a tassels on the tip of its dorsal fin.
Like many fish, this species can change sex. A dominant male keeps a harem of several females. If a harem becomes too large, one of the females may become a male and take on part of the harem as a dominant male. What makes this species unusual is that the new male may revert to the female sex if challenged by a more powerful male. A male can become a female and successfully breed, laying fertile eggs.
