So I just bought a Exoterra Heat Mat (or substrate heater as it's called on the box) and the guy who sold me it said it would do perfectly well with clickclacks. So I get home, open it up and on the instructions it says "Use on glass only". Glass is underlined. Do you think this will be okay on a plastic clickclack or should I take it back? I do have an exoterra glass tank than my baby beardie is currently residing in. What I could do is move him into his 4ft enclosure a little early and put the snake hatchling into the exoterra tank...-sigh- So much hassle. Will this be fine for plastic or should I do all this swapping and moving?
