The Basics of Guppy Fish Disease Prevention

The Basics of Guppy Fish Disease Prevention

As guppy hobbyists we receive a great deal of joy and satisfaction from maintaining this beautiful species of fish. Along with this comes a great deal of responsibility with the priority being to keep the fish healthy and happy. Fish disease is something that is of a great concern to all guppy owners. The best medicine is prevention, but in order to be able to do this one has to be aware of what the guppy may be vulnerable to. Guppy fish disease prevention is something every guppy owner should practice.

Once the disease sets in and begins to contaminate the aquarium it brings with it many distressing factors. These include….

  • The loss of fish
  • The loss of quality breeding aligns
  • Time lost for the selective breeding
  • A great deal of extra time is required
  • A financial loss is realized both in the loss of the fish and the purchases needed for medication.

It can be really difficult for the new guppy owner to be able to identify the various different types of diseases that can strike the guppy. This is why preventative measures are so important.

What adds to the problem with the disease is that there are so many different forms of it. There is…

  • bacterial
  • fungal
  • worms
  • parasites
  • non-contagious diseases

Then added to this are diseases that the guppy may have inherited through genetics which could be a bent spine. These are just the tip of the iceberg when it comes to some of the common diseases that can affect the guppy. Each of these categories has a sub list of the type of damage that can be created. For example, in parasitic diseases there are subcategories such as cotton wool disease, velvet, or ick, and when it comes to the fins and the skin one may be dealing with leeches.

While this may sound most devastating and overwhelming there is much that can be done to prevent a lot of these diseases from striking. One of the first steps to keeping disease at bay is to make sure that the tanks are well maintained and kept clean with the proper water changes. If the environment for the guppy is kept fully optimized then this dramatically limits the chance of disease occurring.

While many of the diseases can be warded off with keeping the tank in good shape, when it comes to the genetic diseases the only preventative that can be taken here is being extra careful when choosing the breeders. Fish that are affected with genetic deformities should not be used for breeding.

In many cases many of the diseases need to be treated quickly and for this reason it is a good idea to have some of the common medications on hand in the event that a disease does break out. This also requires education on the part of you as the owner in order to know which medications are applicable to what disease. This means that you must be well versed in the symptoms of a sick guppy so you know what steps to take.


  1. Up until now I have just been keeping my fingers crossed that my guppies remain healthy, now I will put more effort into learning what diseases can be prevented.

  2. I hadn’t given much thought to genetic deformities and I want to get into selective breeding so this is good to know.
