Tadpole recently turned into a frog, but he won't eat!

If it's been a week or so since he might be stressed by your presence. Maybe try leaving the feeders with him somewhere they can't get away, like a bucket?

Elly's right, it might be stress. Try putting the food in somewhere where the prey can't escape, but also put newspaper or some sort of opaque substance around the glass so it doesn't see a giant "predator" looming over it at all times
