Hi all. I’m new to this. Need help ID this spot on clownfish cheek. Fish have been in QT for 4.5 weeks. I did 2 5 day rounds of Prazipro, then 14 days of Cupramine which ended on Saturday 11/6 (today is 11/9). On 11/6 I did about 30% water change to reduce copper. I have the cuprazorbin there and copper reads 0.0. I just did a 20% water change with slow drip from display tank water. I was going to put the fish in the display and my son said, “Hey, what’s that spot on Bernie the clownfish?” So it just happened in last day or so.
What is the spot?
I have another clown, a six-line wrasse, and an engineer goby in th QT. All bought at same time. No issues on any of them until now. Should I put the good ones in the display? Should I keep them all in QT?
Thanks!
