What is crawling on my bubble coral?

[KatieV]

The sequel to "what is on my bubble coral". You were all so helpful identifying the fan worm a few days ago. Now I've noticed bug-like things running around on it (video) AND a second, hopefully harmless type of tube worm (?) (picture attached). Please help identify.

Appears to be Aptasia over hydroid, Simple kill- using either lemon juice or preferably kalwasser powder mixed into a thin paste, inject it into center core with a syringe and it will melt away.

Don't look like aiptasia to me.
Resemble clove polyp.
