Are Dragon fish aggressive?

Answer 1

The last two answers just before mine are on the money. The most likely answer is that the Dragon fish, as worded in your question is an "Arowana". Arowana's come in different breeds, and the most common you are going to find in North America is the Silver version which originates from South America. They also have a Black version from South America as well. They are aggressive, but as the lady that answered before me calls them as predator, I view that as aggressive. Will they fight with others in the tank? Most likely not unless provoked first. Will they fight thier own kind? Absolutly they will, unless as Copperhead pointed out, you have them in groups higher then five. I have owned four of them, and I killed them on my inexperience at the time. I had a store bought one, that was around 6 inches when I got him back in Feb. I orded 1 small one, about 3 inches, just a baby on ebay, and I put them in a 30 gallon tank togeather, and the bigger one tore the smaller one up. He also ate up my platty's and danio's. He would not touch crickets or any pellets at that time. Now when I put him over in the 75 gallon tank, he was happy to eat crickets, still could not get him on pellets. I got two more off ebay, same size as him, he had grown to 7 inches in a month, and the three of them would take turns biting at each other. The bigger one, the one I had the longest had decided crickets were part time for him, he wanted the rosies and guppies. They died on me because I foolishly added 2 six inch oscars not considering the bio filtration load, which collapsed due to over amounts of ammonia.

Now there are Asian Arowana's as well. They are among the most beautiful fish in the world in my opinion as they come in a wonderous color variety. I personally own a Yellow Tailed Arowana, who is just a baby right now at 4 inches long, and I got him from a neighbor who was going back to Malaysia, and his adult fish had spawned back in the beginning of the year. I'm not going into details on this because they left for Penang two weeks ago and I don't want to be flooded with requests to see if I'd get one for them. I personally would do almost anything for a Blood Red Dragon Fish, as they could go for over $10,000 on the market. The reasons you don't see the Asian ones over here much is because these "expletive" schmucks from CITES have decided, despite several years of successful breeding in captivity, to keep them on the endangered species listing. I personally feel this is wrong, a bunch of BS and it's all about politics, and before the other answer "experts" come and undermine me or interject thier opinons, I want to ask them, just how many of the fish farms over there have you visited? When you've seen and shook hands with at least five like I have, then you got a right to contradict me on this.

Anyways, yes they are agressive, but it depends on your point of view. I personally feel that even though by nature they eat insects, they will eat fish they can fit in thier mouth. To me, that is aggressive.

Answer 2

The dragon fish isn't aggressive...it's a predator. There's a huge difference. The actual dragon fish is an arowana. They grow VERY large and require about 180 gallon tank. They aren't aggressive for a fish per se (aggression has to do with territorialism). They're predators and eat other fish because they're hungry..not because they're being mean. They grow up to 3 feet in captivity.

The other type of dragon is a dragon goby, another type of prehistoric fish. This fish needs an aquarium of about 55 gallons MINIMUM and can grow up to 2 feet long. They are timid fish and never get more than semi-aggressive.

Answer 3

That depends on which dragonfish. Barb and catxcatxx both gave you correct info, but on two different species which both go by the common name "dragonfish".

The dragon goby (Gobioides broussonetti):
http://www.thefishworld.co.uk/id184.htm is a filter feeder that loves bloodworms and won't be a problem with other fish unless your fish are fry or very small (neon-sized). They should be kept in a brackish, rather than freshwater tank, however.

The arowana is most definitely aggressive with other of its own kind if kept in small numbers. They prefer to school in small groups (5-8) and any less will create to much aggression between them. They can be kept with other large, semi-aggressive fish like knives, oscars, pacu, true gourami, or adult plecos that are too big for them to fit into their mouths.

Answer 4

ill take a stab at it....Dragon fish? Like the one they sell at Walmart. If so no they are very tame in-fact to the point of blind. They are sometimes refered to as dinosaur fish too. But i do believe their is another eel looking fish they call Dragon fish but cant recall.

Answer 5

the dragon fish is a dragon goby, or violet goby,
they're peaceful fish and should be housed with peaceful tankmates, preferably in a brackish set up, not freshwater.
