what are they ????
 

Hey guys.......

I have little white things groing in my sump. Seems they got there over night. About half the size of a pencil eraser with what seems to be a fan like a very small duster on the end.

any ideas........ :idea:

Thanks for your help

Pineapple Sponge is my guess. I'd search RC for you to find you some links and more info, but the search page is down :rolleyes:

I would say tunicates.

I have those in both my tanks. I believe I read somwhere once that they are a type of sea squirt (tunicate) like Troy F indicated. They are harmless and don't seem to get out of control. My coral beauty seems to like eating them :biggrin:

Edited,

Didnt look close enouph.... :redface:

They look like a scypha sponge or something similar, there is a pic on melev's id site
