Argulus Symptoms(Fish Lice Symptoms)

The Pros: Both are the best and safest treatment for fish lice and anchor worm
The Cons: Both these products are very hard to find on the market. However, there are other treatments on the market that are just as safe but take much longer treatment.
The best news is, you don’t see many koi that are infested with fish lice or anchor worm.

puncture the skin of your koi in order to have a nice meal of blood. Fish Lice multiple very quickly laying over 500 eggs on the rocks and sides of your pond. In normal temperatures the eggs take a long four weeks to hatch. This is the reason any treatment must be at least 4 to 6 weeks. The hatched young will be eating on your koi for 6 weeks before you can see them.

I sure wouldn't want to deal with Fish Lice! Good luck.

FISH LICE (Argulus) Fish Help/Disease. - Angelfire

Fish parasites are fairly common and if detected early and treated successfully they are no bigger deal than fleas or ticks on your dog or cat. Fish parasites can get into your pond by introducing new fish without a proper quarantine period and examination. They can also hitch a ride in on water plants, snails, frogs, and birds. So what would make you suspect your fish might have parasites in the first place? Heavily infested fish will show various signs of stress. They might scrape themselves against the sides or bottom of the pond repeatedly. In serous infestations fish will rub areas on their skin or fins raw and develop skin and fin infections. Sometimes they will just act funny, or suspend at a odd angle in the water. They might even jump out of the water. Sometimes the opposite is true. Fish will lie on the bottom with fins tightly clamped to their bodies. They can either be extra slimy showing a whitish film or almost lacking a slime coat. They can have irritated reddish spots or streaks on their backs, sides, or bellies. Note that these very same symptoms can occurs because of water quality problems or bacteria or viral infections. Only by identifying a specific parasite can you know the cause of the problem are parasites. Except for the larger parasites, fish lice and anchor worms you will need to use a microscope to identify parasites. In general in the hundreds of times I have checked fish for parasites they have been present maybe 30% of the time and the single most common cause of problems has been water quality.

Fish Lice and Anchor Worm are the only common parasites you can see on your koi without a microscope. If these two parasites enter your koi pond they will attack your koi no matter how healthy the koi are.
