Need Help with a Ricordia Polyp

[THEPHISHGUY]

I have a tank with about 10 different color morphs of Ricordia. All of them are doing excellent. They have grown tremendously and a few have multiplied. However, my favorite one for the past two weeks is totally not happy. Is there any sort of predator of irritant that could be bothering it? It is very perplexing cause nothing else is sick. PLEASE ADVISE.....

Pics would help a lot. Have you changed flow recently? Any corals that could possibly irritate it?

are there any other types of corals near your ric?

Some zoos. Thats it...
