And here is why I've come to hate mushrooms
They seem to just gravitate and move toward SPS. The one on that colony of Snappy's purple valida started out at the base and crawled up to the center of the colony before splitting into 2 lovely mushrooms. I'll eventually have to frag the colony into tiny pieces to get them out of there. Don't know what I'm going to do with that granulosa/loripes frag as the frag plug is thorougly stuck in the live rock.
