The Dragon Fish, shown above, measures about 8 inches total length and is resting on the bottom of one the aquariums in our facilities. Fish farmers don't raise Dragon Fish, so Dragon Fish must be collected from the wild and shipped to us. They ship well and acclimate quickly.

Dragon Fish are usually hardy and easy to keep, and they are very peaceful fish. But they have very small eyes and often have difficulty finding food before the other fish in their aquarium have eaten all of the food.

Dragon Fish are also called Violet Gobies.

Scientific Name. Gobioides broussonetti.

Comments
Dragon Fish have very small eyes and have difficulty seeing and finding food. Be sure that their tank mates don't eat all the food and starve the Dragon Fish. Even though they look ferocious, Dragon Fish are very peaceful fish.

Appropriate Home
An aquarium with at least 29 gallons of water, an exterior power filter with a bio-wheel, and a maximum of 1/4 inch of gravel. Dragon Fish do well in either a cool water aquarium or a warm water aquarium. The water temperature should be between 65 and 78 degrees F. Click here for more about warm water aquariums. Click here for more about cool water aquariums. Dragon Fish are found in brackish water which is a mixture of freshwater without salt and marine salt water with a lot of salt. Dragon Fish do well in either freshwater or brackish water, which is freshwater with one tablespoon of Aquarium Salt added to each five gallons of freshwater.

Recommended Diet
Dragon Fish eat Ghost Shrimp and Black Worms. They will also eat live and frozen brine shrimp. Sometimes they will eat small fish. Click here for more about Black Worms.

Watch your Dragon Fish carefully to be sure it's eating.

Compatibility
Keep one or a several Dragon Fish in an aquarium, but do not keep just a few Dragon Fish together, because the strongest Dragon Fish will make the other Dragon Fish miserable, unless there are several Dragon Fish to distract the strongest Dragon Fish. Good Tank Mates for Dragon Fish are Angel Fish, Silver Dollars, Swordtails, Mollies, and Corydoras Catfish in a Warm Water Aquarium. Dragon Fish are also good tank mates for  Goldfish such as Fantails, Black Moors, Telescopes, and Orandas in a Cool Water Aquarium.

Size and Life Span
Dragon Fish can live for several years and grow to be 22" long, but they rarely grow longer than 15" in an aquarium.

I would say that by the time your Dragon Fish has grown to be 8" it will need a bigger aquarium. We recommend at least a 29-gallon aquarium, which is about 50% bigger than your 20-gallon.

Eventually, a dragon Fish can grow to be 15" long and need an even bigger aquarium. I'd say eventually yours will need an aquarium with about 50 gallons of water.

In spite of their name, Dragon Fish are not very aggressive to other large fish. So your Dragon Fish is unlikely to bother your Plecostomus.

Your Dragon Fish looks thin. Be sure it is getting plenty to eat, which is not easy, because they do not see too well with their very small eyes. Be sure yours gets plenty of live Black Worms, live Ghost Shrimp, and perhaps small fish like Guppies.
