There is still a chance at recovery. I'm not sure how I missed your post, but follow the above advice and he may pull through. Trust me, through advice here and my vet I have now recovered 6 frogs ill from the pet store and another heading in that direction with the start of symptoms from low calcium. It only took my pac 3 days for the tetany to stop with soaks and calcium supplements.

Good luck! We are hoping for you! You can still pull him through this.
