Hybrid 4-line Pictus???

[Columbian Shark Catfish]

Hi, a couple weeks ago i found this kitty at the LFS and he was in a tank next to a 4-Line Pimelodus Pictus. The lady who bagged him for me (and she knows her stuff) said he looks like a 4-line hybrid with something else. i've had a lot of people telling me that it IS a pure 4-line. he didnt look like the 4-line next to him though.

just looks like a young pimelodus sp. could be blochii or even albofasciatus, but its still pretty young. Probably just a blochii
