Hello, this tang has been through 30 days of copper two rounds of Prazi and has been in an observation tank for about 3 weeks I was going to transfer to DT until I started to see this develop so I’ve been watching for about a week and seems the the spots have been showing up a little more. I tried to get the best pictures I could but a little hard. The clownfish are 100% healthy and not showing any signs of anything. I will note nitrates have spiked a bit in this observation tank so I’ve been doing water changes often to get them to come down. I’m guessing lympho? Viral nodules? I’m not sure. If this is lympho or due to the nitrates I think I’ll just go ahead and put them into the DT since it’s much more pristine
edit: fish are eating great I also don’t see flashing or scratching
