his wheezing is most likely the water he was being soaked in getting into his air way and him exhaling water with air if you notice it again i would contact a good herp vet.
I was just thinking that and was going to edit my post.....Ill def be keeping an eye on him..
If it is possible the start of RI do they wheeze constantly or do they have periods of wheezing then stopping then wheezing, etc?
