Dave i was always little suspicious about them being "ammonia poisoned" because even when i checked Turkish forums there wasn't a case where tap water had ammonia to kill fish and i had been using water conditioners to remove ammonia from the beginning. Even when i did partial water changes everyday and there were very few fish to cause ammonia they showed the same symptoms.

Plus the symptom of ammonia poisoning was only red gills. Not red fins or tail. When i shared the photo on a Turkish forum, the guy knew it was septicemia. And the photos of the disease matches exactly with mine.
