Colombo Morenicol Lernex is an effective treatment against skin and gill flukes as well as other visible macro parasites.

Skin and Gill Worms (Flukes) are flattish trematodes, 0.3-0.5mm in size which were previously relatively uncommon in pond fish. However, nowadays they are regularly encountered. Gyrodactylus is the Skin Worm. This worm gives birth to living young and is therefore capable of rapid and massive reproduction. The resultant skin irritation gives rise to thickening of the skin and to the production of a slimy mucous layer over the skin. The Gill Worm is called Dactylogyrus. This parasite lays eggs. It causes damage and irritation to the gills with resultant thickening and loss of full function. Infested fish rub their gills on plants and stones. In advanced cases they swim with the gills permanently opened and they can even die.

Colombo Lernex also works against visible macro parasites such as Fish Lice (Argulus), Gill Lice (Ergasilus), Anchor Worms (Lernaea), Internal Roundworms (Nematodes) and Leeches (Piscola Geometra).
