Hi helpers, I bought this scoly in August, 2013. It was very expensive but it was from a local reefer at a frag swap so it was very healthy. It was doing fine until about a month ago when a small part was covered by the purple mushroom that is in the pic below. I moved the scoly and noticed the part covered by the mushroom had receded. It was deteriorated this month. I feed Ultra LPS pellets but for the last 2 weeks it hasn't had any feeders out and doesn't puff out or push the food to its mouth or even consume the pellets that are near its mouth. The other scolys are doing fine. Please suggest ways to save this beautiful expensive coral.
