Anyone know how to ID these catfish?

I didn't note any differences in the first 2 minutes. What are you referring to?

The only other species that's close-looking and is present in the trade is a paroon shark, which none of these are. There is about a dozen of others in this small family http://www.planetcatfish.com/catelog/family.php?family_id=21 but AFAIK they never enter the trade.

Yeah,as impressive as they are they both look the same to me.

Thanks for your input guys but of the 3 fish I think there are two varieties in the tank.

I am not sure if you'd like more help or not. If yes, as I said above, please, specify what exactly are the differences you are seeing. I think these possible differences are subtle so clear pictures demonstrating your point could save you 3,000 words

This. When I got my new payara, I put up pics of the fish and wrote down the, I think, eight reasons I thought it was one species and not the other. I was able to get a good ID because of that, I think it would help you here, too.
