overviewThe Prehistoric Dragon Goby, also called the Dragon Goby, Eel Goby, Peruvian Goby, or Violet Goby is a brackish water to fresh water fish from South and Central America. The prehistoric Dragon Goby has a long slender body much like an eel with purplish lavender body color.
The Prehistoric Dragon Goby is ideally kept in a 50-gallon or larger aquarium decorated with plenty of rocks, plants, and caves in order to provide adequate hiding places for this typically timid fish. They prefer hard water with an alkalinity of 10 to 20 dKH and a pH of 7.5 to 8.0. In order to maintain these conditions, it is best to provide a substrate consisting of aragonite. The aragonite substrate can be mixed with darker gravel to reduce glare from the lighting.
Although no external differences are known between male and female, if trying to breed the Prehistoric Dragon Gobies, spawning groups of 1 male to at least 3 females is recommended. The male will spawn with several females over the course of a day. Females should be removed immediately after spawning and the male will guard the eggs. After 36-48 hours, the fry hatch and the male should be removed. After the egg sacs are absorbed, the fry can be fed rotifers and "green water" containing algae. After a month, Artemia nauplii can be fed.
The Prehistoric Dragon Goby should be given a varied diet consisting of frozen and freeze-dried foods. In nature this species is an opportunistic scavenger and feeds on small organisms in the substrate, by sifting mud in its mouth.
