Ok finally got the battery and got the gauge working..I think its working..the humidity reading was a bit crazy..was reading 99% but I think that was maybe because of where I had originally placed it, near the water dish and the tank was sprayed a few hours earlier and still had a bit of condensation on the back panel. The temp was very worrying, it was reading 73°F so I have the heater on and monitoring it to reach about 82 that should also help bring the humidity from 84%, where is was reading after moving it away from the bowl, down a bit lower. And if they are offered food but don't eat should I offer again a bit later or wait until the next day, he/she is probably really stressed right now as I have been messing around in the habitat with the gauges n trying to get the stuff moved around a bit better to give him a bit more hiding space.
