Question: Does it harm fish to feed in colder water? I live in southern Tennessee and find that the coppernose bluegill feed quite aggressively even in cold water. I note that the schedule on the fish pellet bag calls for 65 degree but not sure if harm is done by feeding in cold water. Can the fish digest the food?. I feed primarily Purina fish food chow and Purina aquamax 400. Thanks for any feedback.
