I am planning on getting a seperated 10 gallon tank for my two betta fish (VT and CT). the thing is, i want a divider that is strong and not see through. does anyone know where i might be able to find them? I allready checked Petsmart and they have a clear one and the ratings are low. also the tank will be top-less. are my bettas going to jump over and fight? they better not LOL.
