White stuff

[Knoxjoelee]

Not sure from the Picts, but kind of looks like sponge

I know not a great pic. But if it is sponge should I be concerned ?

 

[Clownaround]

Can't really tell from the picture but it does look like a sponge, maybe a white syconoid? From my knowledge there is no danger that comes from them and some act as a filter feeder.
