Does my fish have Ick?
Ichthyobodo is a protozoan parasitic infection seen in fish who are stressed. Ich attacks your fish’s gills and skin. These parasites will cause your fish to have a grey color to their skin. You will notice that your fish will be lethargic, weak, and not want to eat. You may notice that they spend more time near the top of the tank, gulping air or rubbing their side on their tank.
What causes Ick and how can you treat it?
Stress is the main cause of Ich. This can be due to poor water conditions, overcrowding, or illness. When your fish is stressed, it leads to a lower immune system and allows this protozoal parasite to take over. Common things used are medicated fish tanks with aquarium salt, potassium permanganate or copper sulfate.
