go to link below and check out AdCham's profile. I am geting pygmies as well and will house them in a 20 gal tank. You don't want it TOO airtight or things will mold. I think a screen top or a half screen, half plexi might be better.
They are so cute! If this spp. isn't the one you are getting look at the other profiles.
:Hi there, :Can anyone tell me if it's ok to keep pygmy leaf chameleon in a glass tank will a well ventilated lid?
