It's a good thing I never went to med school, because I don't think I could put up with this sort of self-contradicting disease stuff all the time.
Both fish seem stable. Cutting off the antibiotics hasn't immediately spelled their doom, and I don't plan to introduce any other meds unless things change.
Young comet has almost no redness anywhere, and has even come a long way toward repairing the tail fin. I'm a bit worried that I can still see several very small whitish "polyps" around all the fins, which was the original symptom before this all started.
Older comet has perhaps only slightly improved since the last pictures, but there has been no spread either. The main blood supply to the tail is still red and inflamed. It seems like other areas that became swollen would eventually drain and begin to heal, and I hope that will eventually happen here.
Behavior is completely normal. Both of them look at me in the morning like "What the hell? Why can't we be in the main tank again?"
Honestly, I don't know if I would move them back even when they do recover. The two of them are looking cramped alone in the empty 25G hospital tank. They are definitely reminding me that comets are still single-fin goldies with growth potential.
