Aquarium Discus Disease Prevention

Many Aquarium discus fish diseases can be prevented, if fish breeders and discus fish enthusiasts take the time to learn more about how to maintain fish tanks or the aquarium environment that is most conducive to the rearing or keeping of discus fish. It is equally important to know as much as you can about feeding fish, the best fish nutrients, the kind of diseases that discus fish are most susceptible to, and how to identify and treat them.

According to fish experts, healthy fish rarely get sick, even when they are exposed to other infected fish unknowingly introduced into the aquarium. As far as your aquarium are concerned, you can easily improve your discus health and reduce infections, if you setup your aquarium and water perimeter correctly, provide routine maintenance, good nutrition, and minimizing aggression among inhabitants.

It is recommended that you keep your discus healthy in a stress-free environment as this is absolutely the best prevention against illnesses, parasites or discus diseases. Avoid overcrowding discus tanks because this is known to be one major cause of stress and discus diseases. The recommended discus tank size is 30 gallons minimum, preferably tall aquariums. The suggested water temperature is 80F- 84F degrees. Due the high levels of contaminants that are often found in tap water and some bottle water, using a reverse osmosis water filter pump is also an added protection against possible discus fish diseases.

In regards to compatible tank mates, the best advice is to keep them in a species only tank because of the immaculate water conditions they require, when compared to other tropical fish. Although, Cardinal tetra , Corydoras, and Cory cat are occasionally kept in tanks with them, it's best not to tank mate them with other fish that are unable to tolerate the temperature that's ideal for Discus fish. This will cause these species to become ill and eventually contaminating the entire aquarium.


The bottom line is, caring for all pets in general, requires a fair amount of knowledge about the pet, plus time and patience. Because of this, should you decide on breeding or raising discus fish, before you invest your money in this venture, you should do a bit of research online or try to get hold of a few pieces of literature on the rearing of discus fish. Do not wait until after you have brought home your fish -- do this before.

If for some strange reasons one or more of your fish arrived at your home sick, you should at least able to observe its behavior or signs on the body and tell what the disease or problem might possible be. Knowing signs and symptoms of discus fish diseases beforehand, will allow you to save the life of fish before it's too late. However, what if you don't know what fish medication you should use to treat that fish? For this reason, I would say, it's important not only to know about fish medication, you should also have some of the most commonly used medication at hand, before you take home your school of discus fish.
