I have a porites that has been fully extended showing all polyps, but occasionally pulls all its polyps in and sheds a clear mucus. Pretty sure this is usual behaviour for Porites - however recently its been getting white patches. Not sure if it’s flow, lighting or white patch syndrome ? Has anyone experienced this before ?
Will post pics as soon as lights come on.
