Hitchhiker on frogspawn?

[Torq21]

This may not be the right forum to post this in, but I figured I'd start here. I was adding frags to my tank tonight and had to move my frogspawn. When I pulled it out from the rock it was wedged under, it had what appears to be some sort of worm on it. Anyone know what it is?

Looks like the body of a feather duster in a torn tube.

That was my first guess. Would the tube be attached to the base of the frogspawn though?

Yes, it's very common for tubes to be attached to the sides & bottom of rocks, anemones, algae, etc.

Thanks Leslie!
