Couple Questions

[denhay14]

My first question is about my RBTA it has moved onto a new rock which I know "a movving anenome is an unhappy anenome." I didnt know what was happening, but now the tenticles on the left side have lost all the rose color in them. What does that mean?
Other than that it looks better than ever, so help me.


Second question is about my zoanthid. I dont know what the little circle thngs are called maybe polyps? But what ever they are do they spread to other parts of the aquarium? For instance its right by a rock and now there is a polyp in the middle of my sandbed and a new 3 polyp colonie on a rock nearby.

i believe palythoa's will move independently, true zoanthids form a mat and don't move. (unless i have this backwards)

I am pretty sure its a zoanthid, but how can I tell the difference?
