I have this 7 to 8 inch diameter plate coral. It has been doing great for a month since I got it. Today, there is a strip of white stuff (like decay flesh) righ in the middle of the plate arcoss the center. It looks like someone trying to cut the plate in half. The plate still inflates at the two half devided by the center white line.
What is going on with it?
