Just saw this tonight, after I turned off the lights. Ive had this coral for about 6 months now, and the Tank has been running for almost 2 years, never had one of these appear before. Its currently out of the tank obviously. It feels like a stone, not really squishy at all. Would like to know what it is, what causes it, and if harmful how to prevent and/or eradicate more. I tried looking through some older posts, and none of them seemed to either accuratly say what it was, or had any pictures to show what it was, and just to be safe, I need to know for sure what it is I've got. Any help would be appreciated. Thanks!
