I recently aquired a dogface puffer , I had the fish in my quarantine tank and noticed some signs of ich( white spots and scratching) he eats like a pig and already begs for food, I am treating him with hypo and been going fine for over a week now on the treatment. My water conditions as far as Ammonia and nitrates and ph, temp etc... are all very stable and no toxic levels. I noticed a bit of lympho on his tail that has started to get larger. I am positive it is lympho since it has the kinda cauliflower look. Should this be a concern since I know lympho is a viral and normally goes away,also should I be doing anything else? I add selcon to his food and will keep up on the water changes. Thanks
