Can Fenbendazole control Nudibranchs

[Frogger]

I know that people use Fenbendazole to control clove polyps and hydroids. I know it kills all the worms in your tank and will kill the snails.
I have heard it might also be affective against vermetid snails.
It seems to kill snail slugs, worms etc. I am wondering if it would kill monti eating nudibranchs. I am also wondering if it would control acro eating flatworms.

As I have Vermetid snails and monti eating nudibranchs I might be tempted to use it if I know it was going to be affective.

Does anyone have any experience?
