Distribution

Range Description

This species has been recorded from New England south to Brazil, including the Gulf of Mexico and Bermuda. Larvae are carried north in the Gulf Stream, but recruits do not survive the winter (Carpenter 2002). It is found from 1-30 m depth. There is one record (one specimen, 3 cm) from Musquodoboit Harbor, Nova Scotia, Canada (Allen 1980).

Threats

Major Threats
It was driven to local extinction in some localities along the Brazilian coast due to extraction for the aquarium trade (L. Rocha pers. comm. 2009); however, its global population does not seem to be under any major threat.

Wikipedia

Spotfin butterflyfish

The spotfin butterflyfish, Chaetodon ocellatus, is a butterflyfish found in the western Atlantic Ocean, in the Gulf of Mexico and most commonly found in the Caribbean Sea.

The name is derived from the dark spot on the fish's dorsal fin. This, combined with a vertical, black bar through the eye, is designed to confuse predators. The vertical black bar disappears as the fish gets older and other black lines become more prominent. The spotfin butterflyfish can also be found in bays along long island. Many spotfin butterflyfish get sucked up the gulf stream, along with other tropical fish, and are dumped into long island bays. The spotfin butterfly fish is very common and very hard to maintain in a tank. The spotfin butterfly fish can grow up to 6-8 inches. Spotfin butterfly fish are very territorial and will kill each other if put in close conditions.
