I recently picked up a large collection from someone who was getting out of ball pythons. They have all been housed in a rack system together for well over a year, except the 2 hatchlings. No obvious signs of RI and pre treated for mites even though there were non visible.

My question is I’m obviously most worried about nido and ibd. That’s also the main reasons for quarantining.
I’m going to have half of the collection tested in the next couple of days. Full panel tests. I feel pretty confident that if any are sick, it would be more than just 1 and I would be able to pick up on anything floating around the group with half being tested.

If all come back clear, is a full 60-90 day quarantine necessary ?
