This guy came with my green star polyp about a month ago.
He is a cream color with white or yellow tips. He seems to really
extend when I turn the light out (150W MH).

I think it is some sort of anemone because he has moved around,
but he does not seem to harm my gsp.

Should he stay or should he go?

Welcome to reefcentral,its hard to tell from your picture what that is.

That looks exactly like the worm we had in our Nano. My dad had that same worm and it was eating his Pipe-organ polyp from the inside out, slowly killing it.
But my dad put the polyp in a large container filled with saltwater, got some pliers, and pulled that sucker out of the polyp, piece by piece. He was nasty looking when my dad finally pulled it out.....

I'd get that worm out of the polyp before he completely damages your Starpolyp and travels to another. You might have to frag that polyp though, just to get the worm out. But that worm can get pretty big and nasty if you don't toss him......

BTW, that's the head of the worm that your looking at......

I'll take a shot, a majano anemone. notice the clearing of any polyp around it. I vote "Go"

when in doubt, take it out...

This is your first post, nmywrx? Welcome to ReefCentral.....

Thanks for the welcome.

I inspected this thing closer and it was easy to get of the gsp. It was kinda fragile though.
Some of the tentacles came off. I swear the ones that came off are moving on there own.
I hope this thing doesn't multiply.

I am thinking it should go.

Yup. That's the same freaking worm that we had!!!! I'd get it outta there fast.....it did the same exact thing.....it just fell apart when my dad attacked it.

You were right silverfin. It is some sort of worm. The tentacles
were growing out the entire length of the body making look like some sort of anemone.

Crafty sucker!!!

Thanks for help.

Happy to help. Glad that you got the sucker outta there! How big was the worm? The one we had was about 3 inches and the tentacles were about one inch long from it's body.

This one wasn't that big. I would say he was about 1/4 of an inch with the longest tentacles about the same size. Sounds like the one you had was well fed.

05/18/2007, 09:12 PM
Lucky you! Well we'd left it alone for a while, unsure of what it was....but when the polyps started dissapearing, my dad went in there in a flash.....and.....well, you know what happened next.

It's a nudibranch, probably Phyllodesmium briareum. This is a specialized predator that only eats soft corals. The two things it does well are eat and reproduce so you need to carefully check over your coral for the presence of others and egg ribbons. You'll find more information and pictures of the eggs at http://www.seaslugforum.net/factsheet.cfm?base=phylbria

Interesting article. I am new to this hobby and it gets more and more fascinating everyday.

Very interesting. We thought it was a worm but.....wow, we learned something new today. Thanks for that article, LeslieH.
