Marine ich

Latin name: Cryptocarion irritans
Other names: Marine ich
Pathogen: parasite

Symptoms: With magnification of 40x a ciliate protozoan can be seen under the skin and epithelium outgrowth on the mucous tissue, Warts tear apart when you try to separate them, White and gray nodules (spots)

Distinct white or grey patches are skin growths on the mucous membrane which effectively protect protozoa that live under them. Growths are difficult to detach from the skin and they will often burst when a smear is taken.

Cryptocaryosis, which is common in saltwater, resembles Ichthyophthiriasis in freshwater. That is why it is often referred to as Marine ichthyophthiriasis. Disease is caused by a ciliate protozoan which burrows deep into the skin.

How to cure:
It can be successfully treated by SERA cyprinopur because it will also kill free-swimming parasites. SERA cyprinopur can be harmful to certain invertebrates (for example, corals, shellfish, and shrimps), that is why it should be used only in the hospital tank. SERA cyprinopur is used daily for 4 to 6 days. Protein skimmers, ozonizers and ultraviolet water purifiers should be removed from the aquarium. To measure the right dose it is necessary to take into account the amount of water in the tank (including the water in the filter, utility vessels, etc). An insulin syringe, which can be bought in a drugstore, is used to measure out the correct dose (from 0,2 to 2 ml). For treating fish in a separate fish, SERA costapur can be used.

After treatment, fish should not be reintroduced into the seawater aquarium right away, because even a small amount of this medication is enough to kill invertebrates. Fish should stay for 10 minutes in a separate container with clean seawater taken from the main aquarium before they can be reintroduced into the main aquarium.
