Strange Nodule on Multi-Bar Angel

[FlyPenFly]

This is a serious bummer. But this guy just came out of my QT/Hospital tank last week and got added to my macro/lps display.

Didn't eat much in QT but eats a decent amount in the display. Feeding mostly F1 pellets and TDO Chrome Small which it prefers.

No signs of ich/velvet etc as he was in a tank with copper and prazi.

Doesn't exhibit any scratching behavior and swims out in the open if I'm not near the tank. Breathing rate is normal.

Hard to get a photo of him because he is so shy. Will try better but you can sort of see it here. It really most resembles a white headed pimple and protrudes out.

I'm wondering if I need to get him back in QT/Hospital with Melafix or some other treatment or if there's anything that can be done. Really don't want to do that if possible because it will stress the fish and it's barely eating as is.

Okay here we go much better photo.

Look right above the eye.

How long was he quarantined?

 

[FlyPenFly]

3 weeks, was going to go 4 but lack of eating made me chicken out.

Can't really tell from the pic, but your description sounds like lymphocystes

The only experience I have with a pimple like nodule was a flame angel and it was the beginning stages of brook. But since your angel was in a QT for 3 weeks I doubt brook. I have recently read that velvet can be masked by low levels of copper for up to a month. Is it possible he could have bumped into a sea urchin or some other kind of injury?

I'm beginning to think it's lymphocytes. It's one large thing, and not a bunch of small dots like velvet or ich. Lymphocytes seems to be more common in angels.
