saw a dragon fish @ petsmart yesterday. it was very small and was labeled 'semi-aggressive.' any idea if it's a good tankmate in a community tank? was thinking of getting him if so.
most likely that "dragon Fish" is an Arowana and it will grow to about 24 inches and probably eat most of your fish if u put it in a comunity tank. so my advice is probably not to do it. But if it is not a misslabeled arowana and u really want it i would do more research on it to find out more about it.
I believe that is a violet goby as someone posted above. They are often labeled as dragon fish. I think they are pretty peaceful, but might eat smaller fish if they get hungry enough, like small guppies and fish like that. They feed on ghost shrimp and black worms when they get larger, occasionally a small fish. They can get to a max of 22 inches, but I think 15 is more around to what they would grow to in an aquarium. They also have very small eyes and don't see well so make sure they get food before all of the other fish gobble it up before he can get to it. I also think they can live in brackish water so maybe add some aquarium salt if it won't bother your current fish.
Violet gobies arent that hard to find. We havent even established that its FW yet though, could be a draggon pipefish (althought these are ultrapeaceful) or a draggon wrasse
Yeah but only with small fish. They don't have much of an appetite for anytthing big. Most of the ones I've seen probably would struggle with a Neon and full sized ones probably could down a Cory but nothing much bigger.
