Thank you for that, i have PM'd you.

The Bp's are being fed live food - the lady said that that is what is natural to them so that is what she gives them. So going onto frozen maybe become difficult. I asked what size they were on and she said an adult mouse?! is this too big??? they are approx 1ft long. It sounded alittle big to me but she said not to worry as they can eat food items 3 times the size????
I then asked what about when they are bigger with rats ad things and she said that she doesn't feed rats as the snake can get hurt - which i have heard before. She then showed me some giant mice (if you could imagine a rat cross mouse - that is what they looked like) and said that they should have one of those.

Anyway no therometer or any type of temp monitor in the tank, and while there was no light in with them the store is very brightly lit with fluorescents. so they prob are a little stressed, the tank is quite near the floor and the pet store owner has dogs running around all day so not ideal for them at all.
