Ok, so I have a very large backyard pond with a few baby channel catfish, and was thinking I could raise one of the baby channels to a bigger size, I have a 60 gallon with a small perch, medium sized white sucker and a large bluegill, was thinking I could put him in there for a few months just to see how he behaves and eventually put him back in the pond, thoughts? "channel would be smallest at around 6 inches and largest at about a foot" most are about 6-9 inches
