I sense... new rock in my future. I got this freebie mushroom, cool little guy - great orange, green, and blue colors. I didn't know they could move. He jumped off his frag plug, and settled down in the middle of my sps. Like in a hole, deep, where I'll never scrape him out of. I'm wondering what happens as the mushrooms meet the acros - I'm thinking the acros will be toast and I'll be left with a mushroom farm. I'm thinking, "ok buddy, you want to be there - you're going to get blasted with flow and light. You'll move again, and I'll win" Nope - loves it. Mushroom has never looked happier. lol I guess reef tanks are going to do whatever they want to do.
