hmmm, ok I'll be on the lookout for that...I was going by the distance thing (6-8" from beardie being ideal distance). after obsessively measuring from her basking spot, that seemed like the best position...the only other potential issue I see if she decided to jump on it or something...but she's so lazy, not like some of the other beardies that crawl upside down on their screen tops and stuff...LOL
