How Long Does Guppy Fish Live: Factors to Consider

Guppy fish are a popular freshwater aquarium fish, especially in Thailand. They are also known as golden guppies and grow up to three inches in length. The word “guppy” comes from the fact that they swim with their mouth open. These fish have been around for over 100 years and have become more common due to growing popularity of freshwater aquariums.

If you have a guppy fish or if you are planning to get one, here are the facts and factors to keep in mind in regard to their lifespan.

How Long Do Guppies Live in an Aquarium?

In a normal aquarium, guppies can live from two to five years. These fish are omnivores which means they eat both plant and animal food in the water. Upkeep of a freshwater aqua scape is crucial for any long-living aquatic lifestyle that you want your guppy fish to experience as vividly as possible. In addition, guppies require more water changes than other fish species.

How Long Do Guppies Live in the Wild?

In the wild, guppies live for more than two years. This lifespan is longer than that of most aquarium fish. However, if you have a guppy fish in an aquarium, it will not live as long as it would in the wild because of your maintenance and feeding practices. You can expect to see your guppy die after three to five years depending on how well you take care of your fish, including the water quality and feeding.

Who Lives Longer: Male Or Female Guppies?

The male guppy fish lives longer than the female counterpart. Males live through three times as long as females before dying in an aquarium environment. However, their lifespans extend infinitely if they are released into natural waters to spawn with wild-born males and to develop life cycle there among other conditions that are determined by temperature, water quality or lack thereof and environmental hazards (such as predators).

What Can Shorten a Guppy’s Lifespan in an Aquarium?

Some short-livings fish species (such as the bowfin and white bass) can outlast longer-livings fish if not housed with them. These lifespans are usually shortened to up to a year before they get killed or transferred into another aquarium environment variation. For example, when kept in brackish water condition for long periods of time that have an ideal pH level between 6 and 8, these types of guppies can significantly shorten their lifespans.


An important thing to take note here is that the life span of a guppy can vary depending on their individual genetics. There have been reports of male guppies living up to two years in captivity and there’s no telling what other wonderful things can happen with these pets if you provide them with proper care from an early age.

Guppies are known for being quite colorful and interesting animals because of their seemingly unique skin patterns and unusual looking body shapes. Scientific research has shown that the mix of genes in guppies actually determines if a male fish will be more active than others, what color his eyes turn out to be as well as whether he’ll possess an elongated snout which is also called “tadpole face” or “monster head syndrome”. Although male guppies have been reported to be more belligerent when in captivity, the female ones are known for being more inquisitive and curious so whenever you choose between them, those personality differences will play a part regardless of their lookalike appearance.

Water Lighting

Light situations with too much light may cause them severe damage, especially when fitted within water that is not related to their natural habitat. Environmental factors are also important when dealing with the owning of guppy females because not all fish put up well in conditions where water lighting has seen better days. While many female originated stress related deaths have been reported when such effects occur in general home aquariums, occurring within slow-paced tanks can become another ordeal altogether. Dim lighting is one of the major contributing factors with regards to curious fish and glimmers in guppy ponds, so keeping such tanks under wraps or adding a subdued background light during breeding season will ensure that chances are lower for this type of death.

Water Temperature

Water temperature plays an important part as well because all living things need it to thrive whether they are seeking heat or cold extreme ranges around 55-75 F but more frequently residing within ideal water temperatures of 77-82 F. It is prudent to know what the owner prefers for their tank environmental set up as well because selecting tanks unusually sunny on some days will not be well received by fish or owners who have created a proper home away from home where everything runs smoothly because nobody wants any excuses when it comes to aquatic animals dying.

Feeding and Nutrition

Among other choices, live foods are becoming more and more popular in freshwater aquariums today due to their remarkable nutritional value and low cost for healthy aquatic fish diets. In fact, live foods given to carnivorous fish often consume large amounts of food in comparison to herbivores which choose different types of nutritious raw and natural foods instead . Having been continuously used since capture or being fed by the caretaker over time can help make a goby survival rate quite high when kept as pet with such qualifications.


Aside from the responsibility of not subjecting your pet fish to stressful environments, you should also be aware that there are certain factors that can cause stress in a freshwater aquarium. Stressors such as food scarcity and filtration changes or noise may make an animal hibernate for prolonged periods or come out of hiding if it becomes too risky. Other common examples include when ideal water temperature goes unforecastable or any abrupt changes in the environment.

How to Improve Guppies’ Lifespan?

If you want to breed guppy fish, or just want a few to keep as pets, you need to know how to make them live longer. Here’s are some tips on how you can improve guppy fish longevity.

  • Promote a Stable Ecosystem: A stable ecosystem is the most important factor in keeping fishes’ longevity high. You can maximize an aquarium’s lifespan by maintaining a well-balanced ecosystem according to its intended purpose.
  • Provide Necessities: Filtered water must be free from any chemicals and should have diverse naturally added nutrients in your guppy fish aquarium. Without proper nutrition, bacteria can thrive which results to poor water quality that then restricts the abundance of species within a specific environment or may even damage it completely.
  • Right Temperature: Guppies like anywhere between the temperature range of 24 °C to 29°-30 ° C (75°F to 86° F) in their natural habitat but they will tolerate lower temperatures if you live outside those ranges. Below 0 degrees Fahrenheit is not healthy for your pet because this makes it lethargic and inactive. Keep the water temperature between 25 and 27 °C (77°F to 82 ° F).
  • Good Ecological Balance: An aquarium is more stable when provided with lots of fruit, vegetable, live plants and meals as food sources. Remember that your pet fish will eat less often at lower pH levels, more abundant organic wastes should be predominant because this can supply the right balance of waste for proper ecological equilibrium.
  • Maintain Prime Ingredients: Fish flakes, frozen or dried foods. A combination of high protein foods and enriched food is best to maintain the health of your aquarium’s ecosystem.
  • Feeding: Feed your guppies two times a day, morning and evening. Offer them plenty of live food in the mornings- this will provide an energy source for the day’s action too! Remember to feed small meals rather than liberal amounts at one time because these species typically have a high metabolic rate.
