Colombo Lernex Anti Fluke & Worms is a great treatment for Skin and Gill worms, Piscola and Fish Lice and Anchorworms.

Colombo Lernex can also work against Macro Parasite such as fish lice (Argulus) which can grow to 1/2 cm.

Gill Lice (Ergasilus) are smaller than fish lice. 

Anchor worms (Lernaea) can grow to a length of several centimetres.

Colombo Lernex is also good for treating Internal Roundworms (Nematodes).

Leeches (Piscicola Geometre) are worm-like creatures with two suckers - a small one which also functions as a mouth and a larger one at the tail end.

Skin and Gill worms are flattish. 0.3-0.5mm in size these are now becoming more common in pond fish. 

The skin worm (Gyrodactylus) gives birth to living young and therefore is capable of fast reproduction. This results in skin irritation and the the thickening of the skin and your fish produce a slimy mucous layer over their skin.

The gill worm (Dactylogyrus) is a parasite that lays eggs. It causes damage and irritation to the gills with your fish gills thickening and them losing function. Infested fish often rub their gills on plants and stones.

Colombo Lernex Dosage:

20g / 500 litres of pond water.

If required, repeat the treatment after 14 days.
