The 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.

Customer Testimonials

I have a Dragon Goby in my brackish aquarium along with a Green Spotted Puffer and three Bumble Bee Gobies. While he's not the guy that gets the oh's and ah's, I think he is an awesome addition to the aquarium. He loves Hikari Frozen Bloodworms. When I first introduced him to the aquarium he was very shy and hid most of the time, he now explores quite a bit and shy's back into his cave much less. He's grown very fast, out-growing 3 artificial caves in three months and loves to burrow. A great addition to the brackish aquarium!

I own 2 of these gobies and I love them. I hand feed them and they love to be rubbed.

Love my Dragon Goby keep him with a few mollies and a Green Spotted Puffer in a brackish setup. Because of their small eyes and the way they filter feed he has a hard time competing for food. I feed him directly every other day after the other fish have eaten. I suck up either blood worms or brine shrimp in a turkey baster and slowly feed him. He has grown quite a bit and comes out and swims around the tank now. Great addition to my tank.

I have four of these in a 90 gallon tank for about 24 months now. They were purchased at 6" each and are now about 12" long, with one clearly dominant and a few inches longer. They do occasionally fight by butting heads and rubbing against each other, but otherwise co-exist peacefully (no biting or inflicting wounds). They burrow their own hiding spaces amongst driftwood and rock but will also share burrows on occasion. They are fed frozen brine shrimp, blood worms, spirulina and daphnia; they seem to love the daphnia the most. They have uprooted all of my live Sagitaria sp. grass, so I am now trying to grow java fern on the driftwood.

Very cool fish. Mine showed up in a gray color.
