I have several polyps (?) of these on one of my rocks. Any ideas what they might be?

 

[Craig]

can you zoom in closer? looks like it might be an aiptasia

 

[ellebelle]

It's definitely not aiptasia - it looks more like a zooanthid than aiptasia. I have some aiptasia in my tank (sad) and it looks very different!

I have something similar in my tank, but it's more brownish in color, same shape as yours, with a zoo-like look, but I noticed that mine can move around. So far I noticed 2 of them, and they both changed their location, once one was attached to the glass just like an anemone. Maybe they are some type of anemone.

could it be majano? (sic.) another kind of pest anemone. But more rounder than aiptasia

 

[digitalreefer]

It really doesn't look like an anemone at all... it opens up from a polyp just like a zoanthid... could it be a white zoa?

 

[scarf_ace1981]

can you get a closer shot? could be a manjano, although i've never seen a white one, or it could be a bleached/white zoa.

from the pic it looks like an aiptasia to me

Tube worm

Likely just a little tube worm -- like a feather duster in micro size. Nothing to worry about. I think they're pretty when they get big (around 1 cm max).

it looks to me like some sort of encrusting zoa or anemone. it could be a sybiotic zoa that live on sponges. or it could be some type of anemone that ive seen living around gorgonians. but then again that picture is alittle blurry so i cant tell. all i can say is if it colors up its either a zoa or a paly, if it moves around i would say its an anemone
