Ever heard of the saying "guests, like fish, begin to smell after three days"?  Well if you find yourself getting a pet dragon fish you will never have a problem with them sticking around. The dragon goby is also known as the violet goby or dragonfish. The dragon goby is a small fish with very beautiful and colorful scales, but don't be fooled by their beauty as they happen to be scavengers with sharp teeth! Only in the wild that is. Dragon gobies are very small and have been seen to grow between 3-5 in (7.5-12.7 cm) at pet stores. However, in wild algae waters, these can grow up to 24 in (60 cm)!

Dragon gobies can be a great fit for your fish tank or aquarium as these dragons (unlike their name) are quite docile. They can share their tank with other fishes like guppies, platies, glassfish, and more. The violet goby dragon is found largely across the coastal regions of the Gulf of Mexico which also happens to have a lot of manta rays and stingrays and hence these little fishes tend to become their snack.

Dragon Goby Interesting Facts

What type of animal is a dragon goby?

Violet gobies are often considered extremely hostile and are often sold as 'the aggressive fish' but that is not necessarily the case. These are generally submissive when it comes to being tank mates with other fishes and many times these fishes happen to be partially blind too. Having said that, if they are to share their tank with another goby dragon, they become extremely territorial and are not afraid to use their sharp teeth to stand up to the 'aggressive fish' title and become the superior of the two fish dragon.

The violet goby dragon fish is renowned for jumping, hence it requires a larger tank size as compared to most of the other small fishes. It is also seen that dragon gobies are more active at night and tend to hide in the shaded regions of their tank during the daytime. This can be because the gobies are used to living in muddy and brackish waters where the sunlight doesn't reach as much as compared to clearer waters.

What is a dragon goby's habitat?

Dragon gobies or violet gobies live in brackish water with a high amount of salt content. These fishes have small eyes and are partially blind. Due to this, gobies are primarily scavengers and are often seen scooping gravel from the river floor in order to consume the edible content from it while tossing aside the inedible content. They use their sharp teeth in order to scrape algae off the rocks.

In order to keep them as pets in your fish tank or aquarium, it is essential that the dragon goby habitat condition is being replicated.

Did you know...

The dragon goby distribution takes place widely across the Southern part of the USA and Central America. It is also seen happening on a large scale in the northeastern part of South America and the Caribbean Islands.

They are highly susceptible to bacterial infections and are prone to catch diseases like fin rot and columnaris quite easily.

Is the dragon goby aggressive?

Generally, the dragon goby is quite calm. It's partially blind, likes to live by itself, and tries not to take up fights with other fishes. In an aquarium, they are observed to be hiding in shaded regions, away from sources of light, and are active during the nighttime.

These fishes are hostile and territorial in the presence of another dragon goby and can start fighting with them. It is also observed that gobies get aggressive and start picking on fishes that are smaller than them in size. Hence, it is advised to keep these fishes in a separate tank if you have other small fishes or another goby present. However, it is completely fine to surround them with other freshwater fishes like the guppy or glass shrimp preferably of the same size as the goby itself, so that they don't really become aggressive towards these fishes.

Can the dragon goby live in freshwater?

Unlike some other species of goby like the knight goby and the bumblebee goby which are used to living in freshwater, this dragonfish requires a higher level of pH and salinity and thus it becomes very difficult for it to survive in freshwater regions.
