Coral or pest (growing fast)

[Mikeand Mel]

This seems to be spreading fast. I am not sure if it is a coral or something else.
Either way how do I get rid of it off main rocks?

Look like star polyps

 

[Mikeand Mel]

is there an easy way to eradicate?

+1 for star polyps. They are a popular starter coral, but grow very fast. Anyone I know that has had star polyps has had them take over the whole tank. I've never had them personally, but I'd probably remove the rocks and jpick/scrub them off, then return the rock to the tank. Some people have some luck keeping them on a smaller island rock where they can easily trim back the ones that go onto the sandbed, but harder to deal with once on the main rock structure.

Def agree... these fast growers turn into a niuecense
