There are one species and two entire family of fish I know of that are called dragon fin fish, which is what I think you meant to type. The entire polypterus family is sexed by the anal fin. In males, the anal fin is much thicker. My avatar is a polypterus senegalus, also called a dragon fin fish, dinosaur eel, senegal bichir(and a few other names.) If it's one of the others, the scientific name or a picture would help.
Polypterus are the only ones called dragon fin fish that have tubular nostrils if that helps. The other family of fish would be arowanas which have distinctive barbels on their lower jaw.

I hope you have a big tank, the smallest species of fish that are called dragon fin fish grow 10 to 12 inches.
