Today I bought two Pictish catfish, one looks normal, and the other has a curved spine and what looks like short gill plates. Should I return the deformed one or keep him? I kind of feel bad returning him but at the same time would like to let them know their stock sucks. And maybe he can live a normal life with me? Also not sure if it is in their nature to bump into plants and stuff or if his deformity affects his ability to avoid things.
