I signed into the forum just so I could respond to your post. Im so sorry about your little friend, it sounds like you did everything you could for him. I know how frustrating it can be to try to understand what is going on and you feel helpless. Finding a good vet for frogs is difficult too unfortunately which may or may not have helped sammy. It would be so much easier if animals could just talk and tell you what they need! I hope your other frog stays healthy and happy.
