Argulus


Argulus

Latin name: Argulus
Other names: Argulus
Pathogen: parasite

Symptoms: There are attached parasitic crustaceans on the fish body, Fish do not take food very well (low appetite), Fish do swinging movements, Fish feed well, but are skinny, Fish itch (fish scratch on the rocks and other objects), Bloody-redish wounds

These parasites may be observed primarily behind the gill covers and pectoral fins. Once attached, this blood-sucking parasite leaves reddened, inflamed lesions and causes excessive mucous production. It leaves a small rose spot surrounded by a roller. Adult parasites can be observed with the naked eye. Infected fish become emaciated, sway, and rub against rocks and other objects.

Description:
The disease is caused by the parasitic crustacean Argulus which gets into the aquarium with feed and plants from natural reservoirs. It is a translucent, shield-shaped crustacean up to 6 mm in length. Argulus is almost transparent, only eyes and outgrowths are dark. It affects primarily fish in cold-water aquariums. This parasite is motile and accumulates in plants stalking its victim. It will suck blood until it is full. Then it will leave the fish to digest and after that starts looking for another host. The parasite pierces the vessels using stinger mouthparts and will suck the blood of the fish. It can transmit dangerous diseases, such as Spring Koi Disease and viral infections from one fish to another.

How to cure:
The infected fish is put onto wet cotton wool in such a way that it is fully covered apart from the place of attachment. The parasite is removed using tweezers. The fish is then bathed for 30 minutes in a 0.001% potassium permanganate solution.

Medicine:
Sera cyprinopur
0.001% potassium permanganate solution.

Prevention:
Food taken from natural reservoirs should be carefully checked.
