I think I have to say nevermind, regarding my question about the two terrariums. It's important for me to be able to disinfect terrarium properly between animals and I don't see how I could do that with one that has front doors. The only good method I know is to fill them up with a bleach solution and letting them sit for 20 minutes. That wouldn't work and I don't want to have to fill an entire bath tub with a bleach solution.
