Description
This striking butterflyfish is known for its dark, triangular body and distinctive light vertical stripes on its anterior. It is a specialized coral polyp eater in the wild, making it a challenging species for home aquariums. Its vibrant yellow-banded caudal fin adds a splash of color to its otherwise somber appearance.
