Saddleback butterflyfish

The Saddleback butterflyfish (Chaetodon ephippium) is distinguished by its bright white body, broad black band running across its back and dorsal fin, and a yellow to orange posterior. It features an eye spot on the dorsal fin and a vertical, black bar through the eye. Native to the Indo-Pacific region, this species inhabits coral reefs. In the aquarium hobby, it's moderately well-known but can present care challenges, especially in maintaining its specialized diet, contributing to its occasional but not widespread presence in home aquariums.
