Help!

I just bought a nifty little fish from a *cough* rather inexpensive, inexperienced store. He's beautiful, but the woman who sold him to me had very little info about him. She called him a "chocolate knife" but couldn't remember his other common name. He's freshwater, and likes bloodworms. Can anyone help me figure out what this little beauty is?

He's a dark chocolate brown color with a very thin yellow/gold stripe from mouth to tail. He's got no dorsal fin, and his tail comes to a little tiny spade (kind of like a little devil). He's got very plain pectoral fins, and there's one very looooooong fin from just behind his pectorals to his tail. He's not a very flowy, showy fish, but he's about 4 1/2" long. He likes to hide under stuff, and he's very good at swimming backwards.

Any thoughts? I'm a biologist, so its bugging me to no end that I can't find 1) his scientific name, and 2) any other pertinent care information!

you can either post here, or email me at dragon_lady_317@yahoo.com.

Thanks!!!

Is there any way you could post a photo of your fish?

A search on google for choclate knife turned up nothing. Well there was one page that did talk about it in the form of a fish but alas that site was down.

If it does belong to the knife family then it should have "Notopterus" in the scientific name. Here is a link to google image search of some common knife fish.
