Flat worm?

[Texas_Ranger]

Can anyone confirm these as flat worms?

They were all over my rhodactis mushroom, no where else. Any recommendations?

Yes. They look like the photosynthetic type. A pain in the butt, but not the worst pest you could have. They sit on corals and soak up the light, then breed like crazy. A quick freshwater dip and they should fall right off the mushroom.
