Hi,
Thanks for the kind words.
I've never kept them in a rack system, and would be concerned about ventilation. Even though they favor high humidity, air flow seems essential, at least in captivity, if fungal infections are to be avoided. Also, it's difficult to create a thermal gradient in most rack system containers. In a large terrarium, you can provide an ambient of 75-80 with a warm spot (90 F) and containers with damp moss as retreats; also easier to provide a deep substrate - they dig often, and sometimes paw at the container bottom if kept in shallow enclosures.
Sorry if you are aware of this, but please keep in mind that handling by the tail. while well-accepted with adults, does not work well with juveniles., They can spin "up" the tail to a surprising degree. I was bitten by a hatchling Beaded Lizard in this way.
If you have a chance., please consider posting an occasional comment on 1 of my blog articles, as readers would enjoy reading of your experiences. Article need not be directly on point, I can re-locate if need be.
Please keep me posted, enjoy, Frank
