So it's weird my Yellow peel Tang has been in QT for 6 weeks i just got done doing 2 rounds of prazipro and he didn't skip a beat eating like a tank. About 8 days after my last round of prazipro i noticed a little spike in ammonia and used prime because i did not have water ready for a change. The next day i got a nasty bacterial bloom could not even see inside the tank. I did a 50% water change and added carbon. Now the Tang is only breathing with one gill. All 6 weeks in QT breathing fine but today only with one gill and the other gill is breathing normally. Any thoughts? I though flukes but just treated 2 rounds of prazipro, how could that be?
