Orange Kleini Butterflyfish

Description
The Orange Kleini Butterflyfish—more commonly known as the Klein’s Butterflyfish—is a hardy and adaptable marine fish recognized for its warm yellow to orange coloration and bold black eye stripe. Native to the Indo-Pacific, this species is often recommended as one of the more beginner-friendly butterflyfish due to its willingness to accept prepared foods and its relatively resilient nature. It brings constant movement and a bright, tropical look to larger saltwater aquariums.
