bass are good tempered fish as well as perch. bluegill and other sunfish will fight among their own kind. pike will eat whatever is smaller but need places to hide and are timid. smallmouth bass are aggressive and dont do too well from what i hear. not sure about walleye. i know crappie are very nice and are good for a native community. they like the water no higher than 75. pumpkinseed sunfish dont mind the water up to the low 80s, but the others like cooler water. all these fish are notorious fish eaters so beware, anything smaller than they are will disappear.
