I'm not convinced it's ich, but...

One of my angelfishes has some strange white bumps on it's body. I've done a TON of reading, and I think now I am more confused than before!
At first glance, I thought it was missing scales, which didn't totally surprise me because I just added two new angelfish to the tank. But when I took a closer look, I could see that the white spots were clearly raised bumps. I thought it was going to be ich, because I read that sometimes it can appear as bumps rather than tiny grains. I've read a lot about different diseases but none of the descriptions sound quite like what I'm seeing. I don't think it's velvet. Maybe it might be a fungal infection?
Right now, the fish does not appear to be in any discomfort. It is swimming normally, even greeting me at the tank while I was measuring water params. It had a healthy appetite, too.
I'm not afraid of losing the fish...yet... but I don't want to wait until it's too late. I'd rather not start dumping chemicals in the tank. I have colombian tetras and a peppered cory to consider, also, and I read that they both are not tolerant salt/high temp treatment. I will certainly use chemicals as a last/only resort.
So mainly, I'm just wondering if I should go ahead and take action now or wait for further signs of stress.
I think I attached some pics... I hope I did it right, new to this.

If it's largish bumps, it's highly unlikely it's ich. I can't really see clearly in the pictures, but it does look like a bacterial infection. If you need to treat in the main tank, PimaFix might work. It's fairly mild, and shouldn't cause a bad reaction in the other fishes.

It's hard to tell, but if the white blotches I see are your culprit, then it's not ich. It appears to be possibly a a mild fungal infection or slime-coat damage. Both could be the problem since slime-coat damage can easily be a cause for fungal infection. This should heal on it's own as long as high water quality is kept (do water changes every 2-3 days). A fungal medication may be necessary if there is no improvement in a weeks time. Seachem makes a nice one, and I have some that I probably won't ever use if you need it. The good thing is that fungal infections aren't a problem for other fish unless they become damaged and/or stressed. If your angelfish are being beaten on by other fish, then you'll need to treat and remove the problem fish.

Just my opinion I say it's not ITCH. But I would look into fungi of sorts.

Thanks everyone for your helpful replies!!!
I'm glad to hear it's likely not ich, and that if it is a fungal infection the other fish aren't in immediate danger. My fish is still behaving normally so I will continue to keep an eye on him/her to make sure there isn't any alarming changes or anything.

Avalon- thanks for the offer, I really appreciate that. I'm gonna watch it for a few days to see if it clears up on it's own, but can I let you know within the next few days if I think I will have to treat my fish?

Thanks again, everyone for your input. You guys are great!!
