i personally would have two identical hides instead of two unmatching hides, but thats me.. also do you have any difficulty with that large bowl of water or is your humidity alright/stable all the time?
your temps/humidity look good IMO, the warm side could be maybe a smidge higher but thats all in personal preferance. we keep ours about low of 88-high of 91 (warm side temp) variation lately between shelves in the rack system we use. my spider ball is very active all the time while the other five are lazy butts.. so it could be yours wants to be out and looking around. is it close to feeding day yet? he could be hunting around. thermoregulating is normal too, you just simply cought him movign around his tank going from cool to warm side. could be anumber of things. as long as your temps stay where they are and hes not due to eat then i say hes fine, just exploring. two of our shelves use those exoterra temp probes, i like em' and i have two of the other exoterra ones that do time, temp, humidity, all in one.
