A silvery blue body is broken up by ragged red bars, the fins are edged in yellow and shot through with red rays, and there is a dark eyespot at the base of the tail that gives the species its name. Males develop a pronounced forehead hump as they mature. They stay under three inches, they are peaceful, and they will breed in your display tank without any special effort. Care level is beginner.
