Deworming Corydoras drug choice

What drug is best for prophylactically deworming Corydoras of internal parasites? I'm getting in a school of 20 C. similis soon and want to make sure they're clean so they thrive and maybe even breed well for me. Some preliminary research of the usual drugs has come up with the following:

Avoid:
Praziquantel - causes listlessness in cories and discus.
Metronidazole - potentially causes reproductive harm

Candidates (no adverse side effects I could find):
Flubendazole
Levamisole

I'd like to hear your thoughts on these drugs, and from those who prophylactically deworm their fish.

Levamisole.

I battled Calamus worms a couple times . I've tried flubendizole and metro before. One did nothing and with the other it resurfaced (sorry cant recall which did which). Levamisole works great - 2 treatments. Almost immediate results and not much stress on the fish.

Thats just my experience.
