I was lucky to find a nice 8-9" blue channel cat at my local LFS,he was a little beat up,but the price was petty good.So i put him in my tank with my other fish(14" Lima,8" Lima,9-10" TSN/RTC,14"-15" Jadini and a 8" inch Bala shark).This cat seems to be the most aggessive fish in the tank,he is not beating anyone up but he does chase the other fish occaisianally and i have noticed some ripped fins and such on some of the fish,are channels usually aggessive??lets see some pics of your channels if you have any!!!Thanks!!
