red mushroom coral.

This rock of mushroom coral. I started out with just one single coral that I brough for $10 a head at a local fish store. I attach it onto a rock and that mushroom just growing so huge and divided out many other. Finally, the mother head mushroom coral detached from that rock and attach to somewhere else, now leave that rock with full of small mushroom coral. probably 40 to 50 of those mushrooms in that rock.
