Ok, Doughnut is now in a bowl with 1 parts pedialite and 6 parts water, switched to the 50W bulb, his tank is cleaned and has moist paper towels instead of substrate, and I've used spring water for everything. Tomorrow I'm going to get Reptiaid, coco fiber substrate, and more spring water or a water conditioner.

I am scared to take him out of the water because when I do he stiffens up in a scary way. Is it ok to just leave him in there and let him get out if he wants to?

I know a vet who treats exotics but the clinic won't be open until Monday. I called the emergency vet and they don't treat frogs. I'm worried about taking him there if they won't know what to do. Do you think he will be okay until Monday? Is there anything I can treat his eye with right now to help him?

Also, how do I safely transport him in the car to the vet when I go?

EDIT: And thank you again. I really appreciate this because I feel so helpless and stupid right now.
