channels get HUGE!!! hahahah. i always had them as a kid but they always grew too fast because id feed them till their bellys were packed full. hahahah. then after a short while of power eating they would get so big they would either eat my fish or ruin everything in my tank swimming around. back then i used to take them and trade them in. these days id eat the bastards. channel cat is one of my favorite food fish out there
