these toads are no where near as active as some of the darts I have kept. Mine do like to climb but sometimes they stay there all day. of the 5 I have I can normally only see one or two out in the open. It also sounds like the humidity may be just a bit to high. I keep mine more around 60%. I dont mist often at all but I do put in a shallow wate dish for them every so often so they can splash around. I have never fed crickets to them. lots of flys, springs, and woodlice. I have some pretty plump females and the size difference is very noticable from male to female.
you said "she" is around 7 months? is someone up there breeding them and getting them out of the water? not many in the US yet, maby one or two with cb for sale.
these little guys seem to be pretty stress free IMO. even with a move to a new tank, I never noticed any difference in personality.
hope that helps a bit.
there was an incredable disscusion on dendroboard that seth joined in on that was pretty long but I cant seem to find it now

it was not to long after the feb 2010 imports started to come in.
