So i had this baseball size goniopora coral on the back of my tank. Its been there for a while. I saw it last night. Today its gone. no where to be found. in my reefing career of 15 years i have had lot of fish gone missing in a tank but never a baseball size goniopora ! what do you guys think happened ?

It could have lost all tissue to BJD, and it's now unrecognizable or someone physically removed it from the system.
