is this a spionid worm???

[Blitz99]

if so, or if it's another irritant, how do i get rid of them?

If you see a tentacle come out of it from time to time, I'd say yes. They aren't bad creatures but have the tendancy to breed prolifically.

i do see a long white thing come out of it... so how does it bother zoos? does it sting? or is it just the fact that it's brushing up on them?
