strange thing in my sump? help

[zombiereef]

anybody have an idea of what this is? it is about 7mm accross. it has no shell, seems to be some sort of snail or slug, but i cant find anything in my books that looks even close to this. it moves in a couple ways. it will slide over things like a snail, but will also move like an octopus and "walk" over things. i mostly see it layed out flat in a circle, but can be any shape. dangerous? beneficial?

It's a large flatworm species. It is certainly not something you want in your tank...

Certainly has me baffled, but I'm a carpenter and can ID exotic woods much better than exotic mollusks, which is what you seem to have.

Keep him sequestered until you can get a good ID. I recently pulled a zoa-eating nudi from a rock I bought and had to ask on here what it was. I flushed him right away afterward.

Hold onto it until you get a few opinions. It looks really cool, so if it's benign otherwise, then you're in luck.

Please dont put it into your tank, it looks like a clam, snail eating flatworm... something exactly like that killed my clam, i saw it to late and it got away, just toss it, you wont regret it....

Your first pic is just a fragment of a worm. The bigger part is most likely still in the tank.

Had one of these kill a lot of my snails, eventually got rid of it

+1, good point.

Keep your eyes peeled. Maybe put a cerith snail on a fish hook, slap on a bobber, have a soda and wait for the jerk.

ROFL!!!

that would possibly explain some recent astrea snail deaths. if that is only part of it, i will definitely keep my eyes peeled for the rest of it. i have had a half-dead astrea laying on a rock for the last couple days. he's still kicking so far. i'll use him as bait.
