I found a beautiful vivarium that I want to purchase. It has housed fire bellied toads in it before though, apparently 5 of them. I am completely aware that they are toxic. I have two lovely whites tree frogs and I do not want to put them in danger at all. Is there a way of sanitizing the tank or cleaning it out where it would be safe? The previous owner seems to think if I just do a complete water change and a moss change that it should be fine.![]()
