A kittyfishy question.

[Fishowner]

So I been looking at some catfish pics to see what I like. And I came upon the salmontail catfish. Now to me it looks just like a colombian shark. Are they the same fish or two different species?

The salmon tail catfish (Arius septaspis)is native to Australia, and gets to almost 3 ft in length.
Whether the LFS is correct about the ID is another story altogether.
