I remember reading from another thread a while back that they have a Quarantine Room where all new snakes go. I mean, each individual new snake is not quarantined from each other, is my understanding. So, basically, since he only had this snake 3 weeks, then he should be able to get another one and put it directly in the other side of that tank and they can both quarantine together. Yeah, I like the other snake idea more than the exploration idea. But, that exploration area is one neat thing too. I think it depends on the snake. If he feels stressed out in the other area, I think he should be able to go back to the other side where he feels more secure.
