Light brown spots

[jfenton954]

Hi I just got this young orange shoulder tang and she is in my 40g quarantine tank. She's been eating algae very great twice a day. She's been in there for about two weeks now and I just noticed the spots this morning. The tank is a hypo-salinity tank at 1.017. I do that cause the medications are tough on the fish. I've tried googling the spots and keep coming up with black ich and it looks nothing like it and if black ich is anything like regular ich it can't survive at that salinity. Please let me know what you guys think.

I think it looks to big to be ich. Ich looks like the size of a small gradual of sand. Actually if you have had a fish with ich and it makes it through it the next time you see sand on the fish you will swear it is ick. I would put a nori clip out and try to get better pictures then. It's the best method for getting good shots of a tang. If your treating ich 1.017 isn't low enough I believe it should be at 1.009
