Caught this guy under a duncan

[Suneru]

My frag tank is bare bottom. This guy was moving across the glass then got under my large duncan.
It’s been removed, but I’d still like to know what it is.

Looks like a polycladida flat worm. Snail killer .

Thanks for identifying it. Any advice on hunting down any siblings that might still be in the tank?

Will kill coral, clams, etc as well.
