Ah,
You might want to tighten up the quarantine angle a bit if your going to be bringing a lot of animals in and out - there are some really nasty diseases that seem to be airborne and the one that scares me the most has not been nailed down on transmission factors at all from the last I heard.
Do you treat the new arrivals and their housing with P.A.M. or similar to prevent the transmission of disease via parasites as much as possible?
Melissa asked about peoples quarantine regimes in another thread but I don't recall many people giving their "recipie".
Might be a good question for reptile radio or snakebytes - maybe even with the advice from a recognised herp vet who is familiar with the possible risks and best practices.
Sorry I'm rambling again.
