My parameters are 7.4 ph, ammonia 0, nitrite 0, nitrate 7.5. I do 50% water changes 2-3 times per week religiously. More times than not 3 times per week. Temperature is at 78 degrees. I've done some research and talked to some people on a fish disease group. I already had suspected that it might be lymphocystis. I did not post the disease as that and this was the same conclusion that the people i talked to came up with. I first thought it was a fungal disease and quarantined immediately. I treated with fungus clear by jungle. The growths got worse by the day and the end of the treatment. They began looking like clumpy little balls of cauliflower. The research I did indicates it is lymphocystis. Lymphocystis is a viral disease for which there is no cure. I learned that the best treatment is pristine water, little to no stress at all, high quality vitamin rich foods, stable conditions and lots of water changes. I also learned the fish must combat this viral infection on its own and these conditions will aid in the fish having the healthiest immune system possible. Some fish will fight this disease off and never show signs of having it again. Others may continue to have outbreaks through the rest of their lives. I do not consider myself an expert in fish disease by any means at all. This is just my own diagnosis and treatment aided by research and others.
