Treating Fish for Nematodes

Successful eradication of Camallanus worms in guppies and other tropical fish using fenbendazole and levamisole

Over the years, I have had to deal with nasty Camallanus worms several times in newly purchased fish. My article ‘Treating Fish for Camallanus and Other Nematodes’ contains step-by-step instructions for preparing a Fenbendazole-containing fishfood that successfully rid my tanks and fish of these intestinal parasites. I have also described treatment using Levamisole HCl, another highly effective drug.  Article describes the worldwide presence of Camallanus and the related Capillaria parasite.  Photo shows a Camallanus worm slowly being expelled from the anus of a female guppy during the Fenbendazole treatment.  (She recovered fine.)
