Your froggie is adorable!
Sometimes frogs don't eat while they adjust, but 8 days seems a bit long.
I have the same tank, and my baby Gray was absolutely lost with all the space in there, which made hunting a bit challenging.

When I want to keep track of my frogs eating habits, I place it in a deli cup, turn it on its side and put the food in. Smaller quarters seem to get the frogs to eat, even when they aren't enthusiastical about it.
Perhaps you could try something like that?
Hopefully someone else can chime in.
