Black-fin Shark ????

Hi. Visited lfs today, saw a catfish they called a Black-fin Shark. The only info they had on it was that it grew to 6", likes a little salt, and does better in pairs or more. Looked a lot like the silver-tip shark, but body was white and fins were black. Can't find any info on this fish...can anyone give me any other info on it? Different name, maybe?

my guess is it's an arius of some sort, I'd steer clear if I was you.

Black-fin shark is one of the common names for <i>Arius seemani</i>.

My arius seemani was 14 inches at just under 2 years old, in a tank that wasn't nearly large enough for him. I'd been told they stayed 9 inches and under, and that they would tolerate water that had just a touch of salt. Both bits of information were grossly untrue, and to my horror, I discovered that he was a brackish fish that would require MORE salt, the longer he lived, not less. They are definitely neat fish to keep, but pretty specialized to keep well, IMO.

Thanks all. The deeper I get into it the more it sounds like a Columbia cat. (aruis) to big for my tanks.
