hi, I need help making a half land half water tank for my fire bellied toad. I tried Plexiglas and i guess I measured the tank wrong and everything was just ruined.Do you know how much inches i have to cut the Plexiglas to be able to do the 50/50 tank for a 10 gallon and what glue is good to not have the water seep through? I don't like using gravel because I feel like its not safe for the toads. So any other safer ways to make a 50/50 tank would be fine anyways thanks....
