The bubble is sort of the king of the tank but the xenia is quickley overtaking the tank.
The strange hting to me is that the mushroom rock in the front left corner is the first coral I ever purchased and to tell you the truth it never grew. I mean the mushrooms never split or moved to other rocks.... I was able to manually divide some but the mushroom rock just seems to be very retracted and not full. Also it is not reaching out or waving in the current. IT is basically laying flat against the rock.
