Hey guys, I picked up this catfish at Petco about a week ago. It was donated and was told that it was aggressive towards the previous owner's Oscars, and was biting them. In my mind I was thinking "yeah right" so I paid the $5 for it and left. Immediately after I put him in my tank he started displaying dominance over my female red devil. The fought it out for a bit and now get along quite well. I'm not sure what type of catfish he is though. I've searched with no availe and the closest I can pin is a pictus cat. Any help please?!
