That's an incredible price for that Pastel and Spider! From what I can see, whether or not he's actually that bright, he has very nice blushing. I just hope for your sake that the Spider is actually a female, being that they were sold so cheap. Even if they both turn out to be male, I think you got a good deal.
If you're planning on holding the snakes up next to each other, I assume they've already gone through quarantine? Not sure how long you had the others since they're obviously older.
Very nice little collection though!
EDIT: Just re-read the original post. If you just bought the "normal" today she should be in quarantine. Considering you said the YB has been eating weekly, I assume you've had him for some time longer.
