Flatworm immune to Flatworm Exit?

[BurgerFish]

Those green (I think) worms live in the fuge (not in the display).

Flatworm Exit doesn't helps at 2x dose.

Any way to eradicate them? Like Damselfish in the refugium?

Thank

You need to get their eggs and destroy them. I also tried a six line wrasse, cool fish but didnt touch the type of flat worms i had.
