Paratex is a very effective remedy, which adequately cures disorders caused by skin parasites. These parasites, such as skin worms, gill worms, tapeworms, carp lice and anchor worms, occur especially in spring. The higher temperatures cause them to multiply and target the fish. If you have an infestation, Paratex will prove highly effective in killing the parasites. Because Paratex is a medicine, please read the instructions regarding the dosage very carefully.
