That's good to hear! Just to touch on a few points, there is nothing harmful about coconut bark except in the chance that it is never changed, it can harbor bacteria. (Even though it is bacteria resistant to a degree).

Vets I'm sure recommened F/t over live because they have to. There should not be any problems feeding live when supervised correctly. Snakes have been doing it for years, I think they have it pretty well down pat.

As for the oil, I don't know how oil is supposed to treat a mite problem. If there was a problem, that may have been why she recommended paper towels, to better see any mites. A good treatment for killing mites is sticking them with some Provent a mite!

Your set up looks great, if you wanted to make is a little bit more closed in for the Bp, get some jungly background for three sides of your tank. I think it would look just top notch!
