What on earth is this thing?????

I have a bucket of liverock from my old tank waiting for my new tank to come and it has a bunch of these! Tried IDing them the other day but couldnt find anything close. Im pretty sure its the clam eating flatworm. ****

If it's a polyclad flatworm, chances are it's going to eat something you like. Best to play it safe with these guys and evict.

Then again, I had a big one in a 10 gallon back when I started but didn't see it really after I first noticed the surface of my rock moving. I guess whatever it ate that I would have liked, I didn't have yet :P.

Thankfully they are both in my sump. Unfortunately I only see them once in a blue moon, however next time I see them I'll remove them. Not sure how it's still alive since there's not much for it to eat in the sump and I think I first noticed it over a year ago.
