The second is a Pangasius sp; probably P. sutchi or P. hypothalamus; all Pangasius species get huge anyway (even the smallest get to about three foot), so the actual species isn't going to make much difference to it's care.

Just rehome it asap - preferably back to the store eventually they will end up with tanks just full of them getting bigger and bigger until they run out of options... harsh but one batch of them stuck in the shop will end up with them not getting any more.
