As for shyness, is there a lot of traffic walking by the tank? IE Frequent walking can promote hiding. Try dropping in a few .75" fish and see if she eats them, do it regualry to see if she comes out. Feeder shrimps will get her juices going.
It starting to come out a little bit more, usually if the lights are dim though. I've put rosies in with it before and it devours them.
