Flat worm id?

[Swfiend]

Best picture I could get
My friend got some frags and I went to help him dip them and these came off. Real small pen tip size

Dipped in coral Rx these were left in the water but not dead

Acro eating flatworm??


Any guesses to the type? They came off of a war coral

They are purple or very dark brown

Possibly aceol flatworm cause it looks like it has 2 tail endings, but it could also be a tiny polyclad flatworm
