ID a poorly fish please

[SoupDragan]

I've had a marine tank set up for 2 months now, and all the tests show the water is good and healthy. (Will re-run the full set again tonight).

I added 2 Percula Clownfish last Wednesday, and I've just noticed something unpleasant on the side of one of them

Can you help me identify it so I can get the best treatment ASAP?

Picture about to get attached, and if the poor fish does a better job of posing, I'll upload another ...

Could just be a scratch/cut, but being these are clownfish you also have to consider the possibility of Brooklynella. Does it look like the skin is peeling or sloughing off?

Edit: Lymphocystis is another possibility; you describing it as "white bumps, slightly raised" in the 2nd post makes me think it's probably not Ich.

None of those symptoms, and after googling Brooklynella I don't think it's that. These are more defined 'spots'.
