This guide provides you with how to take care of guppies. Certainly, guppies, also known as million-fish, are small, colorful tropical fish that are popular in the aquarium hobby.

Facts about Guppies

History of Guppies

Guppies are small, colorful, and lively freshwater fish that is popular in the aquarium hobby. They are scientifically known as Poecilia reticulata and are native to tropical regions of Central and South America. Guppies are known for their vibrant colors, unique patterns, and distinctive tails, which make them a favorite among hobbyists.

Male guppies are generally smaller, more colorful, and have larger, more colorful tails than females. Female guppies tend to have less flamboyant coloration and smaller tails. This sexual dimorphism is one of the distinguishing features of guppies and is a result of sexual selection, where males evolve more elaborate traits to attract females for mating.


Guppies are known for their prolific breeding habits, and they are often referred to as “million fish” due to their ability to reproduce quickly in favorable conditions. They are livebearers, which means that females give birth to live young instead of laying eggs. Guppy fry (baby guppies) are usually born fully formed and are capable of swimming and feeding on their own shortly after birth.

Guppies do prefer warm water

Guppies are relatively hardy fish and are well-suited for beginner aquarium keepers. They are adaptable to a wide range of water conditions and can thrive in small to moderately-sized tanks. However, they do prefer warm water with a temperature range of 72-82°F (22-28°C) and require good water quality with appropriate filtration and regular water changes.

What do Guppies Eat

Guppies are omnivorous and will eat a variety of foods, including flakes, pellets, live or frozen foods, and even some vegetables. They are voracious eaters and should be fed a balanced diet to keep them healthy and thriving. Overfeeding should be avoided, as it can lead to obesity and related health issues.

Aggressivity of Guppies

Guppies are social fish and can be kept in community tanks with other peaceful fish species. However, it’s important to note that male guppies may display territorial or aggressive behavior towards each other, especially if they are kept in small tanks with limited space. Providing plenty of hiding spots, plants, and swimming space can help reduce aggression among male guppies.

Guppies are known for their active and playful behavior, and they can provide hours of entertainment with their constant movement and colorful displays. They are also popular fish for breeding projects, as they are relatively easy to breed and can produce many offspring with interesting color patterns and tail shapes.

Overall, guppies are popular and attractive fish that are well-suited for community aquariums, especially beginner fish keepers. They require appropriate care and attention to thrive, but they can make rewarding and enjoyable pets for those interested in keeping freshwater fish.

Here are some general guidelines for taking care of guppy fish:

Aquarium setup

Provide a suitable aquarium or tank that is appropriate for the size and number of guppies you plan to keep. Guppies prefer a well-filtered tank with a temperature range of 72-82°F (22-28°C) and a pH level of 6.8-7.8. A tank of at least 10 gallons is recommended for a small group of guppies.

Water quality

Maintain good water quality by regularly testing the water parameters, including temperature, pH, ammonia, nitrite, and nitrate levels. Perform regular partial water changes (around 20-25% every 1-2 weeks) to keep the water clean and healthy for your guppies.


Guppies are omnivorous and should be fed a balanced diet. Provide them with high-quality fish flakes or pellets specifically formulated for tropical fish, as well as live or frozen foods such as brine shrimp, daphnia, and bloodworms. You can also supplement your diet with vegetable-based foods like spirulina flakes or blanched vegetables like spinach or lettuce.


Tank mates

Guppies are generally peaceful fish and can be kept with other small, non-aggressive fish. However, be cautious when selecting tank mates, as some fish may nip at the guppies’ fins or compete for food. Avoid keeping them with aggressive or fin-nipping fish species.


Regularly clean the aquarium by removing debris, and uneaten food, and performing partial water changes. Clean the aquarium equipment, such as the filter and heater, as per the manufacturer’s instructions. Monitor your guppies for any signs of illness, stress, or aggression, and take appropriate action if needed.


Provide hiding spots, decorations, and plants to create a stimulating environment for your guppies. Guppies like to explore and swim in a well-decorated tank. Live plants also provide hiding spots and can help improve water quality by absorbing excess nutrients.



Guppies are known for their prolific breeding behavior. If you want to breed guppies, provide suitable hiding spots like dense vegetation or floating plants for fry (baby guppies) to hide in. Be prepared for an increase in population if you have male and female guppies together.

Health care

Keep an eye out for any signs of illness, such as changes in behavior, appetite, or appearance. If you notice any signs of distress, consult a qualified aquatic veterinarian for proper diagnosis and treatment.


Now you have all steps on how to take care of guppies. By following these guidelines, you can provide a healthy and stimulating environment for your guppy fish, ensuring their well-being and enjoyment in your aquarium. Remember to always research and understand the specific needs of the guppy fish and provide appropriate care based on their requirements.
