In another article that I read a long time ago from: Dr. Gary Aukes; Pharm D, Dr. Brian Aukes; PhD. and I quote "The internal form of Hexamita are flagellated protozoans found in the gastrointestinal tract of a wide variety of fishes. They frequently infect discus. Spironucleus may be a distinct organism from Hexamita, as it is longer and possibly more sinuous, but for practical purposes, both organisms appear to cause similar clinical responses. These parasitic protozoa are very motile. The flagella are usually not easily seen. Many times infections are not apparent. The disease is characterized by poor condition, weight loss and death. The fish may also show excessive nervousness, turn dark in color, and hide in the aquarium". My point is that every Doctors have their own theory and as a hobbyist I read those articles to have a general knowledge about the issue (not claiming that I am an expert). So when I am faced with the issue, I try different suggestion from the expert and stick with the one that works best for my Discus. I believe these kind of forum is good for hobbyist to share their hand on experiences on different issue, not claiming to be an expert.
In conclusion I believe that every living being that live on this earth has certain common needs to survive on this earth, just like human we depend on good quality of air,water food and land to survive and fish they need good quality air water and food to survive too. So when the fish has issue we got to check the basic of their survival that is water air and food. If we can maintain those criteria in an aquarium we will not have any issue on the fish's diseases.
