Live pinkies? i hope not mice, that is far to small for even baby bp's, Remember every week they dont have to eat they are not like us, iv had even my 300-400g girls go on fast for 2-3 months with only a weight loss fo 30-40g after defications. They will be fine, Aswell make sure her hide is small enough that she touches 3+ Sides.... Bottom/left/right/top any of those.. the best hide, will look as if its too small for them, my 400g lavender spider, fits in a small hide, so always make sure hide isnt too but (her being behind it is a sign it may be too large.
