I'm thinking about dividing my ten gallon tank into two parts since it's so big. It currently has one dumbo halfmoon male betta (who is adorable!). I'd love to be able to divided the tank, but I wasn't sure what all that would require. It has a sponge filter and a heater that are both for a ten gallon. I know the screen absolutely cannot be see through or they will stress each other out (plus trying to fight). What would y'all recommend? Divide or no?
