I'd release it into a lake.At least thats what i would do.But if you want to keep it i'd get it a 90 gallon tank,or a 75 at the smallest.

I'd say more like a 10,000 gallon aquarium.I don't even think they make aquariums that big.
LOL

If you walk on the telephone poles above the channels,you look down and see some channel cats like 5 feet long kinda scares me and i've been walking on them for 3 years.

I'd get a 180 gallon tank or 300.But they would do better in a pond or lake.If i were me i'd raise it till its bout 14 inches in a 135 gallon tank and then i would release it into a lake or pond.

They can get up to 5 feet maybe 6 feet.We have em here in ohio in the channels.
