Mueller's Butterfly

Chelmon muelleri. Not as colorful as others in this genus, yet still attractive having a silvery-white body with several wide tannish orange vertical bands, a long narrow snout used to search crevices for food, and a black false eyespot on the rear upper body and lower dorsal fin. In fact, it grows a bump on its forehead that is thought to be used in head-to-head fighting with others in its genus.
