The green one is Green Star Polyps. A very easy coral to keep that many beginners start out with. They can spread quickly and overtake a tank if not controlled. |
The brown guys quickly suck up into the rocks when disturbed. (i tried to get one last night with my tongs and was unsuccessful!)
The green growth I am talking about isn't the Green Star Polyps, but the fern looking stuff to the top of the photo.
