Xenia shriveled from higher flow

I added a little more flow to my tank 3 days ago, it seems it had some negative effects. My Xenia the next day was shriveled. It was still pulsing, but it was 3 times smaller than normal. The heads were tiny, and they looked like pygmy xenia. Also my clown has not been eating right, I think he may have hurt himself. the day after he wouldn't eat. 3 days later he ate a few pellets, but not his normal 6 pellets in one mouthful. I took out the hydor I added.. hopefull things will go back to normal. The rest of my coral is perfect.

 

is this in the 16 gallon? A Koralia 1 is a little much for that; try a Koralia nano

 

I've had the Koralia 1 for 3 months.. it was fine.. I aded a nano to increasse flow towards the bottom. That's when I had problems.. will the Xenia come back... it is bigger today, only half the size it was now, and is still pusling.
