Orange crush disease?

Help! It started as what looked like a mixing of colors in the center of the colony, after two weeks it has become in the middle with colors beginning to mix around the hole. Has anyone experienced this before? I sure don't dont want to loose this colony. Thank!

Same thing happened to one of my chalices recently while the outside seemed perfectly fine, I'm Not sure what caused it. Id dip it, feed it, test kh, ca, mg, and do a decent sized water change. If it doesn't stop or begin healing; in my experience when a colony starts receding in the middle it is a slow recede. Eventually you could take it to LFS and have them cut it up for you possibly then you'd have several smaller pieces that haven't been infected.

Thanks for the info, I'm afraid this one is grown into the structure. I will pour sand over the affected area and hope that kills some good flesh along with the diseased area.
