Scopas tang turns white?

[1602reefer]

Hey all, yesterday I had to use aptasia x to get rid of a minor infestation I had, so I had to turn off all my flow to feed them. It says to leave all flow off for 15 minutes so I did tried to do that... but I had to cut it short because my Scopas looked liked he started to freak out. He started to fly around the tank and turn a pale white color so I turned the flow back on thinking it was oxygen depletion. All my other fish seemed fine. And I do water changes every monday and have to shut off the powerheads and he's never acted like that. I was wondering could he have sickened himself by accidently eating some of the aptasia x? Today he doesn't seem as stressed but he still randomly turns super pale and seems scared of any motion outside the tank. Sorry for such a long post, just don't know what to do...Thanks

My hippo tangs turn pale if stressed or frightened. The blue parts turn almost clear. If it was just a minor infestation, there shouldn't have been enought aptasia x used to be a problem. I've had my tangs for over 4 years and they are still frightened by motion outside the tank. You should be fine.
