About a month ago I added a duncans coral frag to my tank. It currently has 4 heads. Placed it in the sand in a low flow area and it has been doing great. Eating and really coming out and looking full and lush.
However, yesterday one of the heads wouldn’t come out at all and the same thing has happened today. The other 3 seem ok. Looking closely it seems almost like the head has completely disappeared.
Nothing has changed in the tank and parameters are all good.
Anyone had this happen before and is this the beginning of the end for the other 3 heads??
