Mine almost never takes nightcrawlers based on movement alone. That's why it took me so long to get her on them. I finally just got her to where I could rub it on her lips and she will take it, but it took forever for her to associate that with food.

A good rule is not to panic about a frog not eating unless it starts losing weight or you have good reason to believe something bad is causing a change in appetite. Just cover three sides of her tank and keep traffic around her to a minimum for a few days, she'll probably calm down quicker that way.
