To try and bring him/her out of it you should soak him/her in luke warm de-chlorinated water with 2 to 3 drops of honey disolved in the water. Soak the frog for 5 to 10 minutes. You need to maintain temps of 26 to 27 degrees Celcius during the day and 23 to 25 degrees at night. Keep the humidity at 75 to 80%. You don't want to let your frog hibernate the first year. They need to be atleast a full year old before you even think about that. Keep us posted.
