Bass, Butterfly Peacock
The Peacock Bass has three vertical stripes on their bodies and a spot on their tail fins that resembles the eyes on a peacock's tail feathers -- a feature which resulted in their English and Spanish common names. In addition, all adult males have a pronounced hump on their foreheads. Other physical traits can vary greatly depending on the species, individual and stage of development. These include but are not limited to: dark rosettes instead of stripes, light speckles, impressive shades of bright green, orange, blue and gold. The stripes, however, tend to fade in late adulthood.
