Should I be worried (1 Viewer)

I noticed this morning that my toadstool from the frag demo is getting a brown spot where the head used to be. Is this normal, or do I need to do something to help it heal better?

Toadstool leathers tend to be very hardy corals.  They will sometimes withdraw their tentacles and get a waxy look to their surface for periods of time of up to a week or more.  This is normal as the animal periodically sloughs off a layer of skin.   Very extended periods of withdrawal can indicate that the coral is not happy with its environment.  Usage of Phosguard and similar aluminum based phosphate binding agents can cause the leather coral to withdraw as well.  This doesn't seem to cause long term problems for the coral. They are tolerant of most lighting conditions and prefer low current. The symbiotic algae zooxanthellae hosted within its body provides the majority of its nutritional needs from the light driven process of photosynthesis. It will also benefit from additional food such as micro-plankton and baby brine shrimp.

I don't know about a fragged piece, but mine have a mind of their own, similar to my anemone.
