Panacur is used often by veternarians *for treatment of internal nematodes and giardia. It contains the highly effective drug-Fenbendazole. *This medication can be given in 2 ways. *
* Method 1: *dissolved in a gel food at 1 percent by food volume = 1gram per 4 oz of food. *Personally, I use flake or tetra bits *as the food here because it is easy to measure. Take the food you will be using *and in a small pan add some hot water until it becomes a watery paste, add *the panacur *and then add one packet of Knox gelatin -7grams. Mix well. *Using aluminum foil make a shallow 1 inch high mold and pour *the food mix into this . *spread it out so its about *1-2 cm thick, and let set in the refrigerator. Next cut it up into smaller squares *and store *in the freezer. When needed take out one of this small squares and cut it up into to bit size pieces. * I use this *food for 3-4 days in a row , then repeat treatment * in about 3 weeks.

Method 2: *If the fish is no longer eating , it can be tubed into the fishes mouth at a dose of 75-100 mg/kg (2.2lbs), using a syringe.
