I recently set up a 90g native tank with 5 shadow bass (Ambloplites ariommus), 1 orange throat darter, 1 banded sculpin, 2 checkered madtoms and 1 black bullhead. The biggest fish in the tank is the bullhead at a whopping 3 inches. The shadow bass are all right at 2 inches and the sculpin darter and one of the madtoms are about 2.5 inches...the baby madtom is barely 1 inch though! It's amazing to watch them interact with each other and i get far more enjoyment out of my free native fish I collected myself the my store bought tropicals. If anyone in missouri ever wants to trade native fish drop me a line. Any input on my tank setup or suggestions would be welcome as this is my first native tank.
