Flatworm?

[kristan]

This has been sitting in the same spot all day - I'm waiting for the frag inside the bottle to attach to the rubble. Is it a flatworm? It doesn't appear to be bothering anything, but I did lose some shooms overnight a few weeks ago and I'm still looking for the perp...
Thanks

Yes, it does appear to be a flatworm, and is most likely a predator but not of your zoanthids. For that I would suspect a crab or possibly a large Eunicid worm.
