Well, the warm side should be around 80, and the hot around 90.

There should be one hide on the hot side and an identical one on the cool side, they don't typically climb so the vine could be removed to make more space.

They should only really be fed every 7 days or so, and once they get older 10-12 days, and I wouldn't attempt again till she/he has been settled in for atleast a week. Don't worry too much if he/she doesn't feed right now, being moved to a new home is stressful and they're shy.

Also, try to make sure your humidity is around 50-60, if it's not high enough try moving your waterbowl a little closer to or partially on top of your hot side.

Once he/she isn't stressed out it should eat for you just fine.

Also, try prescenting (there are stickys on how to do it, but you can put the mouse in a container with holes in it so that it's aroma seeks into the tank for half an hour or so before you attempt to feed, then dangle the mouse infront of the snakes hide using some tongs and it might be more likely to go for it.

and um... Hope I didn't forget anything, but definately enjoy your new little treasure, they are wonderful creatures
