I knew they'd grow faster at 80 than 60 degree but didn't realize it'd be that much faster. I'll try to keep them in my tank as long I can but they'll likely start getting crowded as they start approaching 4 inches( using a tank divider with other fish). Hopefully pond temps will be at least 70 degrees by then and I can transfer them into a cage. I only got 30 fish as my pond is only about an 1/8 acre and I figured that'd be around 2-3lbs which I've read is the recommend stocking rate by the time I release them.
