A Curious Thing Floating in my Tank?

[TYPHOON]

I Know what floaters are but this is in my Tank and not the toilet, ha.

Ive just set up a Marine aquarium, with a lot of help from Dan51. Since the Introduction of Live Rock and Live sand Ive found I have a small round clear ball shaped thing, no more than a couple of mm across floating around. It has all the consistancy of a Jelly Fish? I know Live rock harbours a lot of creepy crawleys but has anyone else found something similar and knows what it is?

lol it shouldnt grow too much, but might start t swim around like a jellyfish, my nano used to have hundreds of these and then they vanished, i found them quite fun to watch the max size of a hydroid is only a few mm wide im actually looking for questions to answer tonight cos there is nout good on telly

I had this worm thing in my marine tank, it was about 15" and had fangs/mandibles, it used to grab the plant from underneath the sand and drag them under, was weird a bit like tremors.

Sounds like a Eunice Worm, nasty buggers they are.
