Hey guys, I noticed mass that looks like spaghetti on the under side of a rock a couple a weeks ago. After looking around I found another mass and I kept a eye on it. Well tonight I found another mass that popped out of no were in the coner of the tank. Any idea what it is? The last thing I added to the tank was a couple of anemones a couple of months ago (no rocks were added to the tank) besides that I haven't added anything to the tank in over 6 months. The last picture is the new colony.
