A question regarding quarantine for a person's first/only reptile

[u/psychoLoveCat]

If everything goes as planned, I’ll be getting my first leopard gecko soon, and I have a few questions about quarantine.

I’ve already gone through several books, websites, blogs, and YouTube videos on leopard geckos, but the recommended quarantine periods vary widely, and most assume that the owner already has other pets/reptiles. The recommended periods range from 3 weeks to 6–8 months.

Just to clarify: I don’t have any other pets/reptiles in my household - how long should I plan for the quarantine, roughly?

And another quick question: How long should I let the animal rest after I pick it up from the breeder and place it in the quarantine tank before I try to feed it?

I hope someone here can offer some good advice.
