This is a very large, very predatory flatworm known to feed on snails and sometimes mollusks. I had several of these come in on a coral, and it took about every chemical in my arsenal to kill them. Once they make it in to the aquarium, they’re nearly impossible to remove.

Wow, totally wouldn't have thought that was a flatworm either. That sucker is huge, lol
