I assume you are wondering about keeping N. American native perch. No I have not kept one yet, but I do keep native species. Northern pike minnow (squaw fish) . I suggest on perch that you keep the water well oxygenated and 70 degrees or cooler. 75 gallons should be plenty of room for several perch. However I suspect this fish may not tolerate others of its kind and may be territorial. Start out with young specimens if possible as I have had my best luck acclimating native fish to aquarium life.
