This video shows how tangs, and fish in general, travel in schools of several hundred(s) of fish. We believe this may be the Caribbean Blue tang but this is not certain. The video was taken near Roatan, Honduras so it is definetly a Caribbean Ocean fish but the Caribbean Blue tang is seldom seen in groups of more than 10 or so individuals. Although the species of fish is uncertain, it is still a great showcase for the schooling behaviour of fish.
