Klein butterfly fish

The Klein’s butterflyfish (Chaetodon kleinii), also known as the sunburst or brown butterflyfish, is a hardy Indo-Pacific reef fish recognized by its yellow-brown body, bold black eye stripe, and blue-edged dorsal fin. Unlike many butterflyfish that specialize in coral polyps, Klein’s butterflyfish has a more flexible diet, which makes it one of the more adaptable—and occasionally reef-nipping—species in home aquariums.
