What is this? I think I have an aptasia on the rock with the spiral thing. Also noticed those green things on the rock. There is a good amt of them, they look like a green stem of some sort. The Spiral thing looks like it has something growing out of the middle of it. Got the best pic of it that I could. The middle kinda has a stalk in it looks like.

The little spiral thing looks like a type of "tube worm." I have one that started small and has added about a 1/2 inch to itself. It has a "cover" to its' top and therei s a very tiny little hair like thing that comes out and will go back in very quickly if startled. I do not know what to call it. No help I am sure, but you are not alone!

Yup, Spirorbis spp... spiral tube feather dusters.

+1 on the spirorbids worms. The green looks like a macro algae. Perhaps Caulerpa but hard to tell at this stage.

So tube worm feather duster thing good or bad?

They a good.... just another cool critter. But sometimes their population grows a little too fast and you have to scrap them off the glass.
