I've had my Blue Tang for about 5-6 weeks now. He eats like a pig: Seaweed Sheets, Flakes, Rod's Food, etc. He doesn't seem to show any signs of stress. He swims around, doesn't flash up or rub on stuff, isn't lethargic or anything. But he keeps getting what I would call bumps. It doesn't really look like ich, more so like these grey little bumps. I kind of assume it is ich, since that seems to be the thing with them, but I picture ich as more spread and less random. Not 100% Here's a photo I just took of him sleeping... The color is pretty much the same day or night. The symptoms come and go as far as the amount of visible bumps. All other fish has no visible abnormalities. He's small, maybe an inch. I'd love any thoughts or suggestions.
