the moldy sponge

[Anonymous]

On the base of one of my live rocks, there is a growth. its about the size of a small marble, with large open pores, like a big ole sponge would have. only this thing is white, fuzzy looking and almost like its moldy....its got a translucentness to it, but not really....pasty milky white and hairy as if its a giant moldy bread crumb. only theres three of them all within inches of each other, and i think i have one growing on my feather duster, a mere two inches away....

anyone know what these pored moldy bread crumbs are?

thanks!

white sponges.....do they need anything to survive? are they parasitic? how big do they get?

thanks for the response!

they need water ;-) they are filter feeders. I would not stress too much about them. I have plenty that come and go in my tank of all colors. Size is hard to say it really depends on the variety of sponge. I have some that are pretyt big and other that are smaller than a fraction of a penny!

It might be a snail egg colony.
