Thanks guys, yes it has a very large fin when fully extended. I bought these as pictus catfish from my lfs in September and as they started growing I knew something was not right. Now it makes sense knowing what they are. Now the only thing that bothers me is that I just read that they get pretty big and I only have a 60 gallon tank.
I payed under $3 bucks for them as pictus, so I guess I got a good deal on them since I see them going from $15-18 bucks each.
