Flatworm ID please

[Varanus86]

I have located these flatworms and don't want to call them a problem but they are concerning. All the corals they are on appear healthy but they have spread to 3 chalices, an acanthophyllia, and an elegance. The pic is them on the elegance.

Almost look like Planaria. Concerning.. a closer pic like a macro would help. Maybe try picking one off with tongs and getting a close up would help id

These are at the closest focus my Samsung will allow. When I try to move them the break super easy. Thanks for the quick response and hopefully these 2 pics help, I discovered them on the elegance tentacles... at least this coral is right up near the glass.

Looks like your common, and usually harmless, flatworm to me. They can and will explode in numbers if given the chance. I tried manual removal, a green coris wrasse who quickly lost interest, FlatWorm Exit at 2x the suggested dosage, and finally a pair of Leopard Wrasses. The LW's were able to eradicate them from my 120DT within about a week.
