Sick Naso tang!

[jallen]

Hello Everyone,

I have a juvenile naso tang that I have had in my tank for about 2 months. He has been very healthy and is eating well. I feed him a variety of food including fresh and dried algae.

I noticed a bunch of spots on his side and around his mouth 2 days ago, I have since taken him out of the DT and put him in my QT. I am trying to see if the broader community can help diagnose this so I can treat appropriately.

Tank parameters, I need to measure Ammonia but NO3 is 0, pH 8.14, Salinity 1.025. Tank has been up and running for about 20 months.

I have also attached a pic.

Thanks,

Jeff

Bump. Anyone able to identify what this red lesion is on the side of the fish?
