Minimal ich that will not go away!

[Sneekit]

So I have an extremely minor ich outbreak, just 1-2 spots on two of the fish. It will not heal up. Ive been at 86 degrees with .2% salt for 5 days now. Water is pristine, system is 180 gallon. All fish are eating and swimming just fine. Coloration on all fish is stunning. Growth rates are awesome. Any ideas on these rogue spots?

Stock list:
3 x EBJD
4 x Severum
2 x Gold Saum
5 x Blood Parrot
1 x Bristle Nose
1 x Rubber Lip

Parameters:
Ammonia: 0 ppm
Nitrites: 0 ppm
Nitrates: <= 10 ppm
PH: 7.5

Ph is a little high but has been stable since thee tank finished cycling months ago.

The severums are the only ones showing spots. Every now and then the other fish will flash, but we are talking once every couple of days. And we spend a lot of time observing.

I plan on only keeping one Gold Saum and 2 EBJD in the long run aggression permitting.

Most fish are 3-4" and there are no damages due to aggression as of yet.

I had an ick outbreak in my discus+ram tank which is weird because the temp is always 84-86 in there. But a month after it disappeared one of my rams had some ick spots on his tail that for weeks didnt go away... finally i netted him, and rubbed them off his tail and its been 3 weeks now, everything is ok. I guess sometimes the slime coat builds over the calcified ick and it doesn't fall off.
