The only reason I think this is because of the spout.

Does a web come out of the tip? If it does it is a snail called a Vermatid.

[snfkotara]

Are they bad snail? I do have one of these on a acan colony.

Eek. A web? Not like those fan feeler things the branacles send out right?

They can irritate nearby corals. They would cause my sps to necrose.

They don't look fan like. They look more like a spider web.

there is no web that comes out. just a little spout at the top. thanks for all the info guys i was worried it was something bad.

The spouts on sponges have an opaque look. Not completely clear, but almost.
