Yeah, the reason I ask is I can't ID these white spots as ich, there is only maybe 3 spots and more towards the back of the body of my blue, and only on one side, and from images Ive seen of ich on fish it looks, ich looks like there are white specks dusted all over the fish, on my blue tang there's only a few, and the white spots are much bigger I would say from images I've seen ich looks like a grain of salt, whereas these look like a white pin head in size. From doing a lot more reading today and a picture of a blue tang with this virus it looks to me that it's lymphocystis virus, and that would make sense as it's only my blue tang that has shown these white dots, and none of the fish, even the blue tang show any signs of illness, eating and behaving normal.
The only thing that bothers me is these white dots only appear for about 24-48 hours, and I've heard lymphocystis takes months to heal? And the fact they reappear around a month later, which points more towards ich, that's why I was going to do a scrape to know for sure. I'm also tracking these white dots now, mark down the day I see them and the day they disappear and see if I can look for a pattern, that could help me compare with the life cycle of ich and might be another ID form.
Any input would be helpful, could lymph heal this quickly and then come back every now and again? Could this be ich and the white spots are just irregularly much bigger?
Love to hear from the experts
