So i am planning on getting a new ball next week. I currently have a very young ball and plan on getting another young one. I was thinking of getting a 20gL tank and getting some Plexiglas and splitting the tank into two 10s. Do you think this would be possible to split the tanks yet still keep the temps good? I was going to put UTH's on opposite corners and do the same with lights. For the Plexiglas i would put a barrier in silicone to prevent them from getting over the top to each other. Of course when they get a little bigger, the silicone could be removed and the tank made into one 20gL for one of them.
