Diseases are generally not a problem in aquariums which have over-filtered, crystal clear, bacteria free water.
Note this does not mean water which is changed frequently. The idea that water changes create good health is a myth. The idea that water which has “good water parameters” will give good health is also a myth.
One caution about diagnosing fish diseases. Even with a microscopic examination fish diseases are not easy to diagnose. Most hobbyists have only what their eyes tell them to go on as to what any fish disease is. This means that diagnosis of any fish disease is simply a “best guess”. And these “best guesses” are frequently wrong. So keep this in mind in all the following treatment articles.
There are some general articles which will be useful when treating any fish disease:
This is a website dedicated to freshwater aquariums. It is based on SCIENCE AND LOGIC, not on parroted internet “advice”, anecdotal “It worked great for me“, or the marketing hype of some profit-driven marketer.
The listing of some eighteen chapters either below or to the right side leads to over four hundred articles on all aspects of keeping tropical fish. These articles have NO links to profit-making sites and are thus unbiased in their recommendations, unlike all the for-profit sites one will find with Google.
Note that the entire website is “open” in that any written material can be freely quoted and used without regard to copyrights.
The photographs on this website are taken free from the internet without regard to copyright or credits. Copyright does not apply to “fair use” sites. “Fair use” are sites where the author does not receive any payment for their work in any way. The site and the usage have to be for educational purposes only. And the amount of material used has to be “reasonable” and “limited”. This website meets all those criteria.
The author, David Bogert (LaBelle, Florida), has kept aquariums of all sorts and fish of all sorts for over 56 years. He typically had ten large and many small aquariums. But note he is NOT an “expert” on ANY of the aspects let alone all of the aspects of keeping aquariums. The chemistry and biology of an aquarium are far too complex for anyone to be a true “expert” in ANY of the various aspects.
The author, has a BS in chemistry, something which is useful only in the sections on chemicals like water chemistry, rocks, silicones, conditioners, and fertilizers. He has some 43 patents, largely in the field of medical devices. This ability to invent things only helps with some DIY designs. But he has also worked for much of his life as a research scientist doing literature searches, data analysis, statistics, and a little-understood field called “design of experiments” or “DOE”. This experience is very applicable to ALL of the fish-keeping science.

AquaInfo is the website with information about keeping fish, shrimp, crayfish, crabs, aquatic plants and of course the aquarium itself.
FishBase is a global biodiversity information system on finfishes. Its initial goal to provide key facts on population dynamics for 200 major commercial species has now grown to having a wide range of information on all species currently known in the world: taxonomy, biology, trophic ecology, life history, and uses, as well as historical data reaching back to 250 years.
aquariumwereld is the official organ of the Belgische Bond voor Aquarium- en Terrariumhouders vzw. (BBAT) and, since its first publication in 1947, has represented an unprecedented source of information for the members of the Association.
