Until now, combating fish lice and other parasitic crustaceans such as anchorworms (Lernaea) or other copepods (e.g. Ergasilus) was only possible with agents that require a prescription, or which are toxic. The parasites harm the fish not only directly by sucking blood, but also may transfer other pathogens.
Now there is a freely available and highly effective treatment – sera med Professional Argulol. It is based on an active agent combination of emamectin benzoate and denatonium benzoate. The treatment does not only combat the parasites while they are sucking blood, but is also effective against free-swimming crustaceans. The treatment is finished after only 24 hours. Repeating the treatment after 3 weeks is recommended as to combat parasites that have hatched in the meantime.
Very convenient for pond keepers: No water change – which always considerably efforts, in particular with large setups – is required after the application!
