Humidity is kind of high, you might want to try and lower it by either drilling more holes on the tub or putting the water bowl on the cold side. Also, the water cowl should not be really big, just big enough for the bp to drink from, it does not need to soak. Healthy bps do not soak.

Also, I've noticed your temps are rather high... warm side should be between 90-94 F and cold side should be 80-84 F.

Another question, do your digital thermo-hygrometers have probes? If so, where are they placed? Are you sure you are actually measuring floor temp and not air/ambient temp?

Last by not least, you should have 2 hides at least. They should be identical and touching all sides of your bp's body. One on the warm side and one on the cold side.

Just my two cents, hope it helps!
