Naso tang swimming weird!

[Kovenant]

I just noticed my naso tang swimming weird in the upper part of the tank, getting his head out of the water and swimming to powerhead/gyre. I bought it since it was small he has been growing and eating perfectly in my tank for about 4 months with no issues. Here is a video. Any help is appreciate it.

I'm not quite sure what the problem is here. That behavior is called "piping". That can be a result of stress, including low oxygen levels. The white spots on a Naso tang are also a sign of stress (or night time coloration).

I think we need to dive deeper into this, here is a post that gives information about how to get us more information:
