Is this flatworm dangerous?

[Mark Novack]

It about 3 to 4 millimeters, oval, and translucent beige-ish. Its quite visible in this photo on the left at the outer edge of the tissue. I rinsed 5 from a caulastrea. I see a few on this trachaphylia and an odd one here and there. Should I just dip the corals and siphon out those I can't dip, treat the tank or let it be?

Thanks,
Mark

In my op all fw are unwanted. I would dip the corals and invest in an appropriate sized wrasse to control them.

I would dip it ASAP too. I had them once and waited too long and they got out of hand. Won’t make that mistake again

I dipped everything. I only found two flatworms but all the dipped species seem a bit fluffier. I'm sure there was a benefit to the dip beyond the worms.
