I almost forgot. You should also cover 3 sides of the tank/keeper with some kind of background to make the little guy feel more secure. Some of these frogs are private eaters also. if you have a bright light on when they are being fed at night can stress them a little. The little guy might be more inclined to eat with all these conditions mentioned above in not just my posts, but everyone Else's too. They are nocturnal so should be fed at night preferably.
