Identification Brook?

Hi, I'm having some trouble to identify the disease I have in my tank... maybe it's multiple things?

This clown is the one with the heaviest infection. Occelaris clown are hardly effected. There's some white dots and some thrashed fins on a few other fish as well. They've have had whatever it is for more than one week and the status is almost the same. One day they look a bit better and the next day they look a bit worse again, but it's no rapid change in either direction. I currently run an UVC-filter on the tank but it has made no big difference so far (or maybe it would have been much worse otherwise)

So what do you think?

Focus is not crisp enough for me to ascertain with certainty.

These were the best out of houndred attempts.

What would you say with fair certainty?

Grow long have you had them and was there anything new added to the tank? How is their breathing, eating and general attitude? Given that they've been like this for a week you may not have much time left to treat them (if it is brook). Do you have formalin on hand? Those red areas are a bit concerning.

A couple of fish were added a few weeks ago. One of them, an Acanthurus sohal showed a few white dots after about a week. There were a lot of fighting then as well so I thought that it was mostly stress. That fish has no problems now.
All of them are eating well and breathing normal. If anything is different then it's that they are a bit more "grumpy" and fight more than normal. This clown is usually one of the biggest bullies, but she might be a bit more shy now... but not much.

I did some backtracking and it's a month ago I added the new fishes. Problem started a few days later, but then seemed to go away. Symptoms on old fish that now are affected came about 2-3 weeks ago.

As you can read in the stickies, ich comes and goes as the life cycle progresses. Sounds like ich. If you had brook, the fish would be dead.
