Hi TJ:
I have just gotten an adspursus froglet yet I do have adult edulus. In regards to the P. edulus (Kong), he use to eat everything in sight when he was younger, yet now he will eat generally only every three days, and his appetite is much more selctive, preferring crickets mostly.
He use to eat everything, yet now will only take the occasional red wiggler, but as I said mainly crickets (gut loaded of course and dusted occasionally).
I have an Ornate as well, and like the edulus, the same thing has occured as he got older.
I agree with Jace, sometimes we worry because WE want them to eat. If they appear healthy and are showing no signs of ill health then I wouldn't worry. Of course make sure the temp and humidity are OK.
Hope this puts your mind at ease
