Guppies are a popular fish among aquarium owners due to their vibrant colors and peaceful nature. Unlike many other types of livebearing tropicals, these gentle giants thrive in almost any environment with minimal care required on behalf of beginner aquarists! While they’re hardy enough not to be phased by most setbacks – often dying without reason- it’s always a good idea if you keep an eye out for unusual signs or behavior from your pet guppy before taking action against what might have caused its death.

It’s difficult to keep fish alive, especially if you are just starting out. A common problem that causes the death of these little guys is lack or improper care- which can be easily avoided with some knowledge on how best for them.

Why Do My Guppies Keep Dying

If you’re a guppy owner, you’ve probably asked yourself this question more than once. Guppies are generally hardy fish, but they are also susceptible to several diseases that can cause them to die. In this article, we’ll discuss some of the most common causes of guppy death and how to prevent them

 Water Quality

The most common cause of guppy death is poor water quality. Guppies are very sensitive to changes in water quality, and even a small change can be deadly. Make sure you are testing your water regularly and keeping it clean.


Another common cause of guppy death is predators. If you have other fish in your tank that are larger than your guppies, they may see them as a meal. Be sure to keep an eye on your fish and remove any that seem to be bullying or attacking your guppies.

Tank That Has Never Been Cycled

It’s hard to say for sure, but it could have something to do with not cycling your aquarium. This process ensures that all bacteria and algae in the water have been cleared out so you will never see them again!  Cycle a freshwater fish tank by adding some fresh tap or river water into it every week until there are no more deaths or at least fewer ones than before’

You must first cycle your aquarium before adding fish to it. Depending on the size of your tank, the cycling procedure will take 1-2 weeks:

  1. Set up your tank and fill it with tank water
  2. De-chlorinator should be added (Seachem Prime)
  3. Nitrifying bacteria should be added (API Quick Start)
  4. Wait for the beneficial bacteria to populate the entire tank, which should take around 1-2 weeks

Increasing Ammonia Concentration

If you want to keep your fish healthy and happy, it’s important that the ammonia level in their tank never goes over 0ppm. But if this sounds too difficult for something so large of an issue with bacteria converting it right away into nitrates then don’t worry! There is a way around all these pesky problems-it just takes some time on maintenance mode until everything sorts itself out naturally through growth rates

The nitrogen cycle starts when plants take up more than enough fixed carbon Dumpling soil  (which we’ll cover later) causes them to produce excess nutrients including N15158.

Ammonia can be caused by a variety of factors, including:

  • Unconsumed fish food decomposes and produces ammonia
  • A clogged filter can also be a major generator of ammonia
  • Ammonia problems might also be caused by a dirty substrate.

Have you ever noticed how your fish die quickly when it’s high on ammonia? It causes them immediate pain and they just wasted away. If their suffering isn’t enough, we also get these burns that result in slower deaths over time because of how badly burned skin authorizes itself off from its own bodily fluids-the more severe the burn; usually means less chance for survival.


Overfeeding is very dangerous and can lead to a range of issues with your fish. It’s important that you know the right amount for them, so they don’t get too fat or underfed!

As mentioned before – over-flooding leads to many unhealthy consequences such as uneaten food remaining in their tank which increases Ammonia levels due to its natural breakdown products ( Nitrogen ). This means there will be less oxygen available for breathing purposes; risking panfish illness.

Die From Diseases

Guppies can also die from diseases. Some of the most common diseases that affect guppies include:

  1. Goldfish Disease

This disease is caused by a bacteria called Aeromonas hydrophila. It affects the skin and fins of guppies, causing them to become red and inflamed. If left untreated, it can lead to death.

  1. Neon Tetra Disease 

This disease is caused by a virus and affects only neon tetras. However, it can be deadly to guppies if they are exposed to it. Symptoms include lethargy, loss of appetite, and death.

  1. Whitespot Disease

This disease is caused by a parasite called Ichthyophthirius multifiliis. It causes white spots to form on the skin of fish, and if left untreated, it can lead to death.

To prevent your guppies from dying, there are a few key things you can do. The most important is to maintain good water quality in your tank and keep your fish properly fed and cared for. Other things you can do include ensuring that no other predatory fish are in the tank with your guppies and keeping an eye out for signs of disease. If you notice any of these things, be sure to take action immediately to prevent further problems. With proper care and attention, you can keep your guppies healthy and thriving for years to come!


If you are having trouble keeping your guppies healthy and alive, it may be a good idea to talk to an experienced guppy owner or a fish veterinarian. They can help you identify the cause of the problem and provide recommendations for treatment or care. 

Additionally, you may want to consider investing in an aquarium filtration system to help keep your water clean and healthy. With the right approach, you can enjoy beautiful and thriving guppies for many years to come!.
