i dont think if the acurtie tipped it would kill your snake, shouldnt do too mucn dmg, but I have mine velcrod to the glass wall on the cool side, with the bottom of it touching the substrate

what size tank do you have? I have a 20L and I put waxpaper on top of the screen, and cut a circle outta the paper a little bigger than the lamp. i dont usually keep the lamp on, and when its off humid about 55%, and when its on usually 45%
