Is it ok to change the scenery in the tank? Does it stress a beardie out to change small aspects of their tank on a regular basis? I clean my Laz's tank every weekend and change his cool side items occasionally. I have him in a 120-125gl tank so I had to get a little more creative when he was younger to block off half of it so he wouldn't get stressed. Now he's older, about 9months and the whole tank is open for him to roam. No worries, there are lights and probes on each side and in the middle that provide warmth and the proper temperatures. I had a waterfall and pool in there at one time, he really enjoyed the waterfall! Again, no worries--the humidity does not go over 20. Last weekend, I took it out because it's getting cold here and the water won't evaporate as much since heating the tank takes longer. So there is just a hide and some rocks now but I may just put it back because he really enjoyed laying under the waterfall. Should I keep his environment the same??
