New BP's should be left for a full week of no handling after you first get them to let them settle. This is a guideline, not a rule but a lot of us do follow that. This will (hopefully, although not always) help with better eating. Leave him alone and only handle if completely necessary in this time. Your BP will be stressed in a new home with new people, if this happened to you you would go defensive too!

I know it's a pain to have such a beautiful creature and not be able to handle him for a week but you'll have many years to love this guy, a week is nothing in comparison! Change his water in this time of course!

Do not handle for around 36-48 hours after a feed is also a guideline. I leave mine for 48hours before handling again.

A hide in the hot and cold end when you can snakes should not have to choose security over comfort. I have make hides out of plastic bowls by cutting in a door and using a lighter to smooth the edges. Remember changing the enclosure can cause stress too.

Glass tank should have three of the sides covered over

This is not set in stone but from research, this forum and a little of my own experience this is what I would suggest. The other guys are much better in husbandry than I am but handling queries etc and I'm your gal!
