In doing my weekly water change I noticed that one of my serpae tetras is extremely swollen, has bulging eyes and a somewhat tattered tail. He is also all but standing on his head. The tank he was in (have removed to a q-tank) is planted so I had not noticed him until today. From looking at the symptom chart in a box or Maracyn, I think it is popeye. The bloated body could be dropsy but there isn't any pine-coning of the scales, red streaks or spots or bleeding. I read a couple articles on popeye on the web and some said to just monitor rather than treating with antibiotics but I think he is pretty bad and may not have time to be monitored. I have started treatment with Maracyn 2. Anything else I should do?
My water parameters were as I would have expected, ammonia and nitrite at 0, nitrate at about 15 with pH at about 6.4. This was after the water change of about 25% but the tank has been running since December so I wouldn't think they would have been any different before the change other than the nitrate would have been a little higher.
Also, I have looked all other residents over pretty closely and all others look to be fine.
