I'm a bit worried that my whites tree frog Steve might be sick. I bought he and his brother from Petco just under two weeks ago and his brother has started growing already but Steve hasn't grown any bigger. Then starting last night Steve started opening and closing his mouth frequently with a little popping sound (sounded like when a bubble pops). It wasn't the big yawning type thing that I've seen James do when he sheds, Steve isn't opening his jaw that wide. He was a little less interested in his crickets last night too. He ate two of them when I tong fed him, but wasn't interested in going over to hunt for them. Today I gave him a honey bath and he was shedding while he was in the bath, so I don't know if that's his only problem but I read that respiratory infections can cause a clicking/popping sound so I want to make sure it's nothing serious. I did hold him up to my ear and didn't hear any wheezing or labored breathing. I'm planning to call the vet tomorrow morning (she isn't in on Sundays) but I was hoping to get some help from you guys too. Am I just an overreacting new frog parent or does this sound serious?
