The males have a yellowish-orange head and a grayish-brown body. Females are not as attractive with their dark gray body, yellow tail, and blue line behind their eye. This fish has large teeth that extend out of the fishes mouth even when the mouth is closed.This is the most aggressive of the dottyback family.In dottybacks, males result from female sex change, and at least some species apparently can reverse their sex (male back to female) in certain social contexts.This fish will grow to 5 inches in length.All dottybacks feed primarily on small crustaceans and zooplankton, though some may consume polychaetes and small fish. Offer enriched mysid, chopped shrimp and frozen carnivore diet.Dottybacks are a group of small, colorful basslet-like fish that inhabit the crevices and small caves of the coral reef.Dottybacks can be kept in smaller aquariums, although larger tanks with plenty of live rock are preferable. They are territorial and will defend the area they have claimed as home quite aggressively. Housing several dottybacks depends on the size of the tank and the amount of hiding places available. There is some success with introducing several dottybacks at the same time, this allows each to establish a territory to defend, without giving an advantage to one. Once a dottyback has becomes accustomed to a tank, it is usually difficult to get another introduced without being attacked. Dottybacks vary species by species in aggressiveness, and care should be taken when deciding which to introduce to an aquarium community.Dottybacks are easy to feed, and frozen foods such as Mysid shrimp or Brine shrimp are readily accepted. They are also known to feed on small bristle worms, and have been introduced to tanks to help control excessive bristle worm populations. Aqua-cultured dottybacks are also fed pellet or granulated food.The family of Dottybacks are well known for their elusive nature. These fish tend to stay within their crevice or cave until it is time to feed. Their color is usually quite dramatic and they are capable of changing their sex. When eggs are laid the males are known to pick up the eggs with their mouths in order to keep them aerated.
