i was sitting on the couch looking into my tank as im sure all of us spend a lot of time doing when all of a sudden some sort of sea star came crawling out of a hole in my LR and right back into another. it happend so fast i only caught a quick peek at it. it was black with white dots and maybe 3 or 4 inches across and very thin. any clue what kind it was. im hoping to see it again and maybe snap a picture.
