chain pickerel, are the biggest, i dont know about wv, but in nh at my lake house they can get 30 inches we caught a monster that was over 40 inches a couple weeks ago, id say 200 gallons for a 2 foot, it would be interesting to awuascape it considering this fish makes itself at home along weed lines
but also you could have grass pickerel and another typ in between that dont get nearly as big
