ID .. Maybe Feather Dusters???

[brizzo]

For the past 8 or 9 months, these little tube creatures have been growing all over my tank. Last night I think I got a glimpse of what is to come. I had no camera last night, but one actually appeared to be a "red featherduster" .. but very very small.

I haven't seen one other actually "open", but when I do water changed, or when bothered, they seem to secrete a kind of stringy goo from their body that sticks to the rocks; like spiderman :P They're also quiet brittle



They even grow on my hermits and snails!!



Bigger area of them, crappy picture.




Any ID's for these??
