New pacman frog not eating !

[Guenhwyvar]

I wouldn't try even a little new born mouse until he gets bigger, so you can be sure he's healthy and if anything goes wrong you can be sure it wasn't because you tried bigger prey items too early. the wild caught frog is probably carrying the chytrid fungus, which is the leading cause in the frog epidemic right now. It can also be carrying parasites that'll transfer to your frog if he eats it. Keep an eye on it for dark shedding.
