I am new to the SW world and just cycling my 1st tank.

Last night I noticed these on a piece of Live Rock in the tank.

Are they good / bad / indifferent?
I like the looks of them but just don't know...

They look like a species of star polyps.

I wouldn't be concerned. You might want to isolate the rock so it won't spread to other rocks as it grows. I have my GSP rock on the sand by itself.
