I tried pretty much all different types of food and she wasn't taking it. Then I had an issue with petco that prevented me from getting fish, so I decided to take the opportunity to starve her out. There were a few fish in there, but they're too quick to net them out; I figured it wasn't enough to sustain, so she would still seek out more food, even if she did catch one or two. The first night I didn't give her anything; the second night I put 2 pinkies in there, and she didn't eat them; so last night I added a shrimp. I checked this morning, and she ate it!! Woo!! Very satisfying when I saw that. Not sure that means we're over the hill, but it has been established that she will resort to eating it.
