Orange shoulder tang black patchy spots

[cashmilladakilla]

Hello everyone, my orange shoulder tang over the last few weeks has gotten these black patchy spots on him, they started off subtle but over the last few days they have went nuts, he is also flashing (he has his entire time i’ve had him, 2+ years) I am setting up a quarantine tank this weekend and i’m going to take him out and get him some medicine. Does anyone know what’s wrong and what medicine or antibiotics would be best for him? (sorry the pictures kinda suck I am not at home right now and it was very hard for the person to get proper pictures of him)
The clearer picture of him is from a few weeks ago, it’s the one I took, but now as you can kinda see in the more blurry one he has more dark patches and is very pale skinned. Thanks for any help

These looks to be bite marks an also bacterial and I recommend quarantine of this fish using seachem Neoplex. The fish is also Very thin and what foods are you offering it?
What tankmates are in with it? There is light evidence of fin nipping also

I had one in a clients tank that was eating food. And started looking like that. But she wasn’t feeding any algae based foods. It looks malnourished from wrong diet. Start giving noir and seaweed pellets immediately.

This is not a complete diet for this fish. It needs meats and fats besides algae based foods. LRS herbivore frenzy is a good based food as is plankton, chopped krill and mysis shrimp as examples

I agree, the fish looks thin. In addition, it’s kind of pale and tattered looking. Do you ever see it scratch on things in the tank?

Nori, mysis, even when they're on sale grab little neck clams from the store and pop em in the tank. Fresh ones that is.

I agree on the variety of food and the herbivore lrs would be the best long term. I used the nori and seaweed select to get the one I had back to good health in 2 weeks by increasing the algae in the diet right away. It developed the off colored dark spots when it was malnourished and looked the same as this one does now.
