is she looking up while she's cruising the tank or just being still? mine do it all the time while they're cruising. and sometimes they just hang out staring up (or sleeping.. not sure) with their head resting on a branch or vine. i don't really think it's anything to worry about... or, if it is a problem, i've never heard of it! congrats on the new baby! she looks alot like one of mine (my fave!) beautiful!
