Trying to figure out how he passed. He was fine a few days ago but I noticed he looked incredibly dreary today and his condition worsened up until now. Wondering if maybe he wasn’t eating because his insides look kinda sunken but I’m not sure if it was a parasite cause his feces looked fairly average instead of white. The discoloration makes me wonder of my ammonia reader was outdated and that’s what killed him. Any thoughts?
