Alien worm?

[reefer2011]

I found this wormlike creature in my seahorse tank. Any idea as to what it is? It is translucent and sticky.

how big is it

I am pretty sure it is a medusa worm. It was about 2" in my tank but when I was trying to get it into the cup it got cut in half so in the pic its about an inch.

I have to agree with you it does look like a medusa worm
