We build these with our in-house laser CNC machine. This means perfect dimensions every time.

Easy assembly and installation. If you are having trouble installing/positioning the divider: simply put a small piece of toilet paper/paper towel under the suction cups to keep them from sticking until you have it where you want it. It is also easiest to install with the tank on it's side.

Perfect for separating young and aggressive fish.
