Dwarf Hawkfish Video Stock Footage
The dwarf hawkfish can reach 7 cm (2.8 in) in total length. The dorsal fin has ten spines with numerous tassels on the tips of the spines. The anal fin has three spines and six soft rays. The pectoral fins are thick and elongated and spread out when the fish is resting on the substrate. This fish is pinkish-red and white in color with vertical banding or mottling. 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.
