I always quarantine rescues. Doesn't matter where they are coming from, they go to a different room. As for my breeders it depends largely on who I am buying from. Honestly, chances are if i'm buying from someone though it's for a reason, and their animals are going straight into the chin room.
If I know the breeder in question had say a fungus outbreak a few months prior to my purchasing I'll put that animal into quarantine, as stress can bring out fungus just to be sure.
