yellowish white puff balls on my LR??????

[MEDHBSI]

Ok so i was looking at my tank today and its relitivly new (6 months) and there are like 8 yellowish white fluffy looking balls on one peice of live rock they also have a tube coming out of them. There about 1/4 big


now for my other question i also saw what looked like a snail without a shell zooming all over my glass, i looked up flatworms and it doesnt look like that hmmmmm basically exactly like a snail with no shell its the oddest thing

Does anyone have some insight to this bad/good sorry for no pictures i dont have a digi cam

First sounds like a sponge.

I've had those snails appear out of nowhere as well. Eithe it grows a shell later or those ones don't have shells I never found out. It's black right? Not something to worry about.

I'm fairly certain most any sponge is desireable, they're filter feeders and help keep your water cleaner. I have two or three that I can see in my system, I'd say there are probably more that are not visible, tucked away inside the rockwork.
