I would find out who manufactured the tank and contact them to see if the tank has tempered glass!!!

If there's no sticker or no evidence that there was a sticker than it's probably not tempered, or at least on the sides it's not. But knowing the manufacturer will help.

I have read on the internet that if you used polorized sunglasses you can see little circles left behind from the heat process if its tempered, never tried it my self though
