I know by experience arboreal agamidae and iguanadae must have the air flow in a " tank " envorionment or they will crash and burn with a week or shortly there after .

I need to know more about this, some of my observations lately seem to correlate in this sense. However my cage are basically air tight, yet my dragons fair well and reproduce in them. But I am sure they are not perfect in anyway. Nevertheless I do think air movement may have a physiological benefit.

Id like you to share your ideas on this if you don’t mind.
