Anyone know what this is?

just saw this haven’t seen it before. Any ideas? The first picture is two little tentacles the second picture is tiny flower looking things. Both in the same rock

Second pic looks like tube worms/ feather dusters, first pic I'm not 100%. Does it retract into the rocks when you disturb it or does it move?

Not sure if it retracts like aptasia. They’re really small and I only see them when my mushrooms close up to feed.

Could you get a clearer pic?

That’s about as good a pic I can get. After looking at Melevs critter ID page I’m pretty sure the first is a Spionid worm. I’m leaning towards feather duster for the second but I won’t know until I can see if it retracts like an aptasia which I can’t do until the mushrooms feed again

+1 on tube worms!
