I am currently in the process of getting a new cage set up going for my two crested geckos. They are currently in two separate 16x16x20 ZooMed wire cages, as they are a male and a female and I do not want then fighting or breeding. However, they have always been housed right next to each other where they can see, smell, and talk to each other which they do quite frequently. Which is why I would like to get one large Exo Terra glass terrarium and try to separate it with some clear plastic material, have holes drilled in it, and seal the edges so they will still be able to communicate and interact. My question is, what material should I look for that would be safe to use to separate the terrarium into halves? It would obviously have to be safe for animals and not give off any toxic fumes or other substances when consistently wet or exposed to a heat lamp. I also need advice on what to use to secure the divider to the inside of the tank, such as an epoxy or something. This would also have to fit the previously listed criteria. Thank you for your help!
