catfish id

So I have recently bought some bagarius species and need help for identification of them. First of I thought it was a B Lica and a B rutilus and B sp unknown. And im confused. And my local fish shop got some home and they don’t know where they come from either. I have some of them and also a B...

B. Filamentosum (piraiba) or B. Vaillantii? My lfs said that this fish is a piraiba but I think it's a B. Vaillantii or even a B. Rousseauxii. I just need the pros to id. Thank you

took a look at the picture of the Internatinal Game Fish Associations Picture of the world record channel catfish. You should notice something funny and obvious. (Tell me if u notice).
