Just as an update, I had one more frog die yesterday. He started behaving the same way the female had, trying to crawl out of the tank. He looked quite red and his skin was ragged looking. Isolated him and treated him with antibiotics because it seemed to work last time. Unfortunately he passed away after about 4 days in quarantine. I'm not sure if it was the same thing as before since it had been a couple weeks since I finished treating and the frogs seemed to be doing well. I'm sure there was some early sign that I was missing until he started trying to crawl out of the tank. Figured I'll keep updating this thread in case anyone else finds it helpful.
