How often does everyone feed? I no longer have a bunch of small guys, but they are all still growing. I have Sunfish, a yellow perch and a bullhead probably all between 4”-7”. I want to maintain optimum growth without over polluting the tank. Do you’ll recommend once daily? Twice daily? Intentionally skipping a day? If you skip a day is there any increase in pestering each other? Also, does anyone think that the cooler temps for temperate fish leads to any slower of a metabolism than tropicals.?
