Due to the low host specificity of the parasite, Ich infection is known from all freshwater fish systems examined. However, the susceptibility and the impact differ between host species. Rainbow trout , catfish and eels are highly susceptible fish species and uncontrolled infections lead to almost 100% mortality.
The following is a list of aquarium diseases. Aquarium fish are often susceptible to numerous diseases, due to the artificially limited and concentrated environment. New fish can sometimes introduce diseases to aquaria, and these can be difficult to diagnose and treat. Most fish diseases are also aggravated when the fish is stressed.
In most aquarium tanks, the fish are at high concentrations and the volume of water is limited. This means that communicable diseases can spread rapidly to most or all fish in a tank. An improper nitrogen cycle , inappropriate aquarium plants and potentially harmful freshwater invertebrates can directly harm or add to the stresses on ornamental ...
The symptoms and life-cycle are generally similar to those of Ichthyophthirius in freshwater fish, including white spots, on account of which Cryptocaryon is usually called marine ich. However, Cryptocaryon can spend a much longer time encysted. Fish that are infected with Cryptocaryon may have small white spots, nodules, or patches on their ...
Infected fish often display signs of discomfort, frequently scratching against objects in the aquarium. The primary cause of an Ich outbreak is usually stress, which can result from factors such as poor water quality, sudden temperature changes, or the introduction of new fish without proper quarantine.

A medicated fish bath (ideally using aquarium merbromin, alternately methylene blue, or potassium permanganate and salt), [6] is generally a first step, as well lowering the aquarium temperature to 75 °F (24 °C) is a must, since columnaris is much more virulent at higher temperatures, especially 85–90 °F.

Fish may not always display the characteristic white spots. Ich sometimes limits infection to the gills and the only sign that a fish is infected is an increase in breathing rate, lethargy, and clamped fins. If left untreated, in a small volume of water such as an aquarium the infected fish can quickly succumb to the rapidly multiplying parasites.
