Can Flash Photography Freak out an Anemone?

I took about 5 or 6 picture of my Sebae Anemone with the FLASH a few days ago. The next day he was in a strange form. first he shrunk to about 1/6 of his normal happy size. His greenish Brown color was a little darker than normal. About 12 hours later he was back to normal size and color. He proceeded to do a series of strange moves over the next few hours.

From his normal spread out happy state he would fold the outer inch downward, then extend his inner self from 2 inches out from his mouth upward a little, extend to a large cone and then go back to his normal happy state again.

He did this about 3 times in about 2 hours. He NEVER detached from his rock nor moved in the tank. He is 100% healthy looking now and was throughout his moves (except in the very beginning).

Nothing changed in the tank. The parameters have been good and the same for months.

Could the Flash been the cause?

This is where he starts to rise from the middle



This is when he goes to the Cone



This is when he went from the Cone back to Happy



...and Happy again.

 

I don't know if it can or can't but what I do know it that anemone do some funky stuff with or without our intervention

 

If the light was intense enough it may have scared it or bothered it - doubtful though. I wouldn't worry too much, anemones are strange creatures and it was probably just having a bad day.;D

 

Do you feed it? If not then it would take an awfully long time to produce enough waste product required to poop - which could explain it's actions.

 

About once a week.
