Any idea what these might be on the coral plugs?

This one is definitely an Aquilonastra starfish (known in the hobby as "Asterina" starfish); I can't say for sure on the other one, but if it's a hard tube, then it's probably a vermetid snail tube.

Looks like a bristle worm and a astrenia starfish.. some people hate them some love them..
