Crested Goby

The crested goby is a small but stout fish, reaching a maximum length of 10 cm (3.9 in). Its body appears compressed and a crest extends back from the middle of its eyes. They have six dorsal spines with the fourth spine being the longest, and 16–20 pectoral fin rays which reach beyond the start of the anal fin in adults. The tail is wide and round. Both sexes have reddish-brown to olive mottling along their head and bodies, but those of the males are more extensive and darker in color. The females cheeks are covered with pale spots, also with several pale lines behind eye, while males have black and orange spots on the first dorsal fin, which change to black and violet during breeding.

This widespread species occurs throughout the western Atlantic Ocean, from South Florida and Bermuda, throughout the Caribbean, and along the coasts of Central & northern South America.

Crested goby feed mainly on algae, but are opportunistic feeders and will take small insects, crustaceans and molluscs.
