Lernex-Pro is an optimised version of Morenicol Lernex, developed for the treatment of resistant skin and gill worms in ornamental fish. Lernex-Pro is based on the latest scientific knowledge and contains high quality anthelmintics against which no resistance has yet built up. Lernex-Pro is therefore highly effective in the treatment of resistant skin and gill flukes. The presence of these parasites can only be determined under the microscope.
