My clownfish has had this white particle on his body behind his fin for about 4-5 days now. It's not flat and sticks out a bit off of his body. There's only one in that spot and nowhere else, which makes me question if it is ich. None of the other fish (chromis and banggai) show any spots and all three are eating and acting completely normal. I haven't added anything new to the tank for a long time, other than a powerhead.
Here's a video, it was hard to get a good picture of it. My clown is too fast for my camera
YouTube - Is this ich?
It could be nothing at all, just a sand particle or something, but I'm going to be away from home for a month so I thought I'd ask before I leave.
