About Modest Butterflyfish

The Modest Butterflyfish is a small, compressed laterally-flattened fish with a yellow-tan body and distinctive dark bands running vertically. It has a white face mask and dark eye-bar, with subtle white markings on the dorsal and anal fins that give it a modest appearance compared to more elaborately patterned butterflyfish species.
