I would like to house my male and female beardie in the same 100gal tank to conserve space in my room, yet I do not want any breedings just yet as they are only a year old. I want to find a suitable barrier to section off the tank equally that would be easy to install, and also keep the dragons safely separated for the time being. Any suggestions on what I should use to do so? I can get pictures of the tank if needed. Thanks in advance!
