Some people put food in a water bottle top and float it. They figure out how to tip it over.
You can put a mirror beside her for a few minutes.
I put a ton of floating plants in both my girls' tanks and they love exploring in the tangles.
Also if you feel Ike investing $8 and some time in creating a daphnia culture, they like to chase down and eat daphnia.
I am planning that next.
