camalanus worms in my community tank

[PolyptRus]

About a week ago i noticed one fish had a worm so i began treating the tank with the fenbenzadol after three days of treatment the worm was still there no other fish have any worms showing is the fenbenzadol not working? I heard that typically after the first dose the worms should start dropping in only a few minutes

I know some members have had success with fenben buts it's via food not water. Levamisole is the most accepted treatment for cam worm. If fenben is not working, you may want to consider switching.

I add about a teaspoon of fen to a gram of food and let it soak in food for a half hour.
I looked up levasimole an it seems really expensive
