Ok so what are your surface basking temps? I see stick ons for temp gauges --- you want 2 digital probe thermometers --- next what bulbs are the in the domes ? I dont see a long tube UVB -- this is a must --- if your using a MVB in one of those domes it is inadequate for UVB rays and the further away from the basking area and w/ screen hes basically getting no UVBThis is the 40 gallon setup.
Are you using a MVB? those are ok if your using a Mega Ray or PowerSun - those provide good heat but you still want a long tube fixture -- here are 3 that are goodWhat UVB bulb do you recommend.
It is possible for brumation but if it's summer time where you are it would be odd-- zoo med digital probe thermometer- let's get the tank temps and uvb on par then go from there w/ his behaviorBrumation?
