Rocks for a vivarium
I used to have a tropical fish tank and now the kids are going for a beardies instead. When I had the tank I had some really nice rocks that I collected from a beach years ago. I still have them in the shed with the other tank stuff. Was wondering if there are any kinds of problems with using this in the vivarium for make "cave" or basking shelf. Any particular rock a problem? Any particular precautions to be taken?
