What might this be?
 

:question:Over the last few days I have noticed this thing, on one of my mushroom rocks. This part of the rock was not visable until recently so who knows how long it has been there. The pictures are sorta crappy......... I apologise.

some kind of small anemone, cant remember what thier called but not really anything to worry about. they dont seem to need light from what ive seen

pseudocorynactis. ball anemone

Yup +1

They almost look like those tiny red feather dusters I've seen... http://www.advancedaquarist.com/issu...002/invert.htm and I also saw them for sale on an american website somewhere.
