Awesome cat! Cephalosilurus was actually the fish that got me into keeping monsters. I especially love them because I've never seen a more grumpy fish. Mine literally used to get mad at ornaments that got in his path while swimming and bug out on them. He pushed, pulled, bit and bulldozed rather than deviate from his course as if to say how dare this thing not move when it sees me coming. Plus I loved the belly flattening begging he used to do as he pressed hard against the tank front with his mouth pointed up out of the water.
