This was not there a week ago, in the past three days these white globs have gone from a spot to a 4 milimeter glob. They grow faster than Anthelia which is crazy and at this rate I worry they will overtake my clove polyp. Clove polyps grow very slowly so I don't think this is a sprout but I'm not very sure. They are located on only one or two of my clove polyps. I don't think its a sponge because sponges don't grow this fast. Can anyone tell me what this is? Thanks.
