they call me fish geek ;p
I think the mat corals are green star polyps. They will spread rapidly. I love mine. And the white things are just a type of worm that makes a hard shell and is stationary. I forget the name now..I hate when that happens. Anyways they are harmless. I have thousands of them on the rocks, glass and even the snails shells lol tank looks great by the way!
