Check out these SWF Hitchhikers!

I ordered the green star polyp which came today. It is huge in my 24G nano and when it opens it will be the center focus in the tank but I noticed something emerging and didn't pay much attention thinking it was just the coral opening. Then it started moving across the coral! Then there were TWO! Are these anenomes?
The first two pictures show the critters on the move. The pictures were taken about 15 seconds apart. The third picture shows the Christmas Tree Worm on porites rock (upper right corner) and the Green Star polyp rock with the moving critters to be identified.
Any Ideas on what the roving critters are?

Looks like maybe a small BTA, nice hitchhiker!

I had those on one rock. They spread quickly and walk around to hide. Get it out---get it out.
