Sore spotted on my clown

[cvanchuck]

So about a month ago I noticed an ich breakout in my reef tank. I went to PetSmart and purchased a 55 gallon kit and did a water change from my main st to that and then transferred all of my livestock to that tank. I’m leaving the livestock out of the main dt until January to let the ich die off. The only left in dt are a few hermit some snails cleaner shrimp rose bta and corals. I am coming up on thirty days of copper safe treatment where my levels have been ranging from 2.8 to 2.2. Per my Hannah checker. Also did a prazi treatment twice since I noticed brown specs on my yellow tang. Over the past two weeks I’ve noticed this sore on one of my clowns. It’s my female. She’s acting normal and eating and swimming well. Should I be concerned?

Could be a secondary infection from copper treatment (which is an immunosuppressant).

I would start food soaking vitamins to help boost the immune system: https://www.reef2reef.com/threads/vitamins-herbal-remedies.304287/

If it starts looking worse, antibiotic treatment may be next: https://www.reef2reef.com/threads/antibiotics.283711/
