I've kept many types of fish over the years including fresh and saltwater. Now I want to try something different. I just tore down my 125 saltwater tank and built it into a wall between the laundry room and rec room in my basement. I want to give freshwater natives a try but I can find very little info. Can anyone give me some stocking ideas? I'd like to keep it fairly peaceful and avoid anything that could outgrow the tank.
