What Might This Be?

This came in as a few polyps on a zoanthid rock. I broke them off and placed them by themselves. The centers are a glow in the dark type of green and they have doubled in number in about four months.

Any idea what exactly they are?

Some type of star polyps I would say.

I agree they look like star polyps. Cool colors.
