sick 2 yr old pacman frog

I'm working on uploading a picture. Sorry for the confusion the substrate in the tank has been changed monthly. It's the big bag of substrate that's over a year old.

You may want to make a vet apt then, the substrate being a year old is what made me think he was toxed out. But if its being changed monthly it shouldn't be that unless you expand the with nontreated water.
