I have had Blues in what may 10 acre lake, (which is only about 5 acres do to lake of water), for about a year now. This past summer they REALLY ate the pellet feed really well. They seemed to feed more in the deeper water while the CC's fed closer to the bank. Along with the bream.

Personaly, I think Blue cat is by far the best fresh water fish you can have... \:D

Give us more details on the lake, what eles do you have stocked in there?
