Hi, I got a Kole tang 5 days ago. She appears to be a very shy fish, either hiding when she see my shadow or bumping on the glass or chasing her own reflection in the corner. Finally yesterday, she started come out to eat occasionally. She look healthy that is a good relief. Still, I am not risky my display tank by all means, I quarantine all new fishes and do preventive cuprimine treatment before release any to display tank. However, I read copper treatment could damage Kole tang. What would you do to quarantine this type of tang without using cuprimine? lower dosage, or does it make sense to do preventive hypersalinity quarantine? or just observing she for longer period of time?
