My yellow tang have been in QT for over a 5 weeks now and ready to go back into the main tank this week. But a few days ago I notice he has a ulcer and what looks like hemorrhage around the affected area. Since then I have applied Waterlife's Myxazin for treating bacterial infection. I have used this before with success, but this time it is taking a lot longer to heal up. I have been doing 25% daily water changes and reduced feeding.
Do you think I should move him back into the main tank where the water quality is much better than QT so he might have a better chance of healing? Or should I continue to used medication in the QT?
