Hi just wanted to post an update on the grey tree frog. I think I may have inadvertently done something that snapped him out of his slow spell. Things carried on for roughly a month with him not eating and only occasionally making a trip to his dish. It has gotten much colder here so with the forced air on most of the time now humidity levels have been very difficult to maintain in the tank, especially with his heat lamp on. I tried (not successfully) to make a DIY Dripper (bottle with pin holes) that ended up dripping way too fast. About 10 seconds into the virtual rain storm he began croaking and continued for a few minutes. The next morning he was out on top of his hide and took three crickets by tong. Prior to this he would completely ignore or back away from this method of feeding and would not go after any free roaming crickets when they approached him. It has been a few days now and he has taken 2-3 crickets per day since then and has been out and about at night. Hopefully this continues. Thanks again!
