What is this creature?

Anyone know what this is? Good? Bad?

Kinda waves its body like a sting ray when it swims.

Acoel flatworm I think. Bad

I agree with it being a flatworm. Not necessarily bad, but can quickly reach plague proportions.

I tried manual removal with very limited success, then a green coris wrasse that helped some before it went rogue. Freshwater dips for all removable corals certainly took care of the ones on the coral, but they quickly returned. I then resorted to Flatworm Exit, using 1.5x the recommended dose. It didn't have much more effect than the coris wrasse even though I dosed twice, a week apart.

I then decided to try the natural route again and purchased a Blue Star Leopard Wrasse and a couple weeks later, another. They are not only strikingly beautiful fish, they spend every waking hour hunting among the rocks for whatever tasty morsel they can find. I haven't seen a FW in months thanks to them. It was very cool watching them carefully pluck FW's from the flesh of my Elegance coral without harming the coral in any way.
