Feldman is no longer in this world He seemed to pass quickly, so I don't think he suffered needlessly.
Now it's time for me to learn from my mistakes. I tested the water in the new hospital aquarium post mortem:
7.5 PH
0ppm Nitrates
0ppm Amonia
Water Tests from Community Tank:
7.4 PH
0ppm Nitrates
0ppm Amonia
I think my biggest mistake was misdiagnosing body fungus (bacterial infection) as true fungus (fungal infection)
I tried to treat the wrong illness and that cost Feldman precious days. After the fact, I learned that it's OK to treat for both diseases at the same time if you choose the medicine correctly - so I'll probably try both if this kind of event ever happens again.
I really appreciate your guys' help for this. Please take a second to go through all this and let me know if I made any other mistakes along the way.
