So I got my first ball last week at a reptile show(juvi male fire) and I had his tank setup exactly the glass tank sticky thread above. I also have the same exact thermometer in that thread as well but can't figure out a stable way of mounting it so he doesn't knock it over which he has done repeatedly and I feel bad because I keep having to open his tank up to flip it over so I can see it. I tried just setting it in the corner and also using a suction cup but it wasn't strong enough, he kinda likes to rest part of his body on it for some odd reason as he peeks out of his cool side hide and then likes to hang on it. I don't wanna use tape cause that's just a bad idea and I thought about Velcro but idk if that's a good idea either. So I was hoping someone here could throw me some ideas as I don't wanna keep intruding on him to fix it. Although it doesn't seem to bother him a whole lot and he's already fed for me once but I'd rather not have to worry about stressing him out. My other solution was just to pull it out and leave the probe in there as the temps have been very stable with my thermostat regulating the uth but I don't wanna rely on my analog thermometer alone for the ambient air temperature. Thanks in advance for any help!
