Well, it looks like I killed him with the pedialyte or he was ready to expire on his own. After the bath and noticing the spots I did put him on moistened paper towel and went running. When I came back he was dead

I want to thank you all for the great advice. I will take it all to heart for the other frogs and any future frogs. I will be changing their substrate today with the treated water.

I hope I didnt waste too much of anyone's time
