I have been dealing with flukes for a month now and used Prazipro with no success. Freshwater baths have helped but only temporary so yesterday i removed all fish and put in QT and did a fenbendazole 12 hour bath. The main tank is now fallow and will remain for at least 30 days however i just noticed hundreds of little white things crawling all over the glass. Are these flukes looking for a host which cant find without any fish in the tank?
