Help identify please.

I just noticed these a few months back. Have searched for pictures but have not found any. The closest resemblance is a tunicate. They are small approx. 1/8", jelly like, very invasive,
spread like aptasia, close up when touched like an aptasia, soft jelly like, I find them on the underside of frag plugs and shaded areas of rock. I've used aptasia x to get rid of them

I would guess some type of ascidian...... there are several types of star tunicates that look similar.
