With its red markings brilliantly displayed against a blue background and yellowish belly, this species is the most colorful of all the sleeper gobies. The females of the species are rounder in shape than the males and the yellow banding on the edges of the dorsal and anal fins is more pronounced. The Peacock Goby achieved great popularity during the mid-1980s and the 1990s. It has now been widely bred in captivity and is one of the most often seen eleotrids.
