I just upgraded my hermit crabs from a 20 tall to a 20 long and I put background along the back and sides of the tank, I’m wondering, when I put the UTH on the side, should I put it under the background or can I put it over the background? The UTH has no adhesive and I’ve used it on multiple tanks, I just tape it, I’ve already got it taped over the background and it’s staying on fine. It’s pretty old, so nowadays it doesn’t get super hot, definitely not hot enough to come anywhere near burning my skin, so I don’t think it’d melt the background, so would it be an issue to just put it on top?
