Hi,
What kind of substrate(s) do you have in the enclosure?
Have you found any poop in the past 2 days?
What temps are maintained in the enclosure?
What are you feeding the frog? Are you dusting the feeders with calcium powder
What size feeder is it?

Make sure he has de-chlorinated water to soak in every night.
Provide a - clean- shallow soaking dish (water should not be above his chin)

He needs to soak ! NOT TAP WATER! .

If you do not have amphibian safe water de-chlorinator-get it asap !
In the meantime use bottled 100% spring water from the supermarket.
