View Full Version : Can Fenbendazole control Nudibranchs

06-27-2017, 08:16 PM
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?

I don't know about it killing nudibranch but from experience it definitely did not kill any of the vermatid snails in my tank.
In my opinion it should only be used as a last resort to control clove pylops as it kills so much of the beneficial fauna that lives in live rock.
