Aquarium Setup

  • Tank Size: Guppies are relatively small, but they thrive best in a tank of at least 10 gallons. A larger tank provides more stability in water parameters.
  • Filtration: A gentle filtration system is essential. Guppies prefer calm water, so avoid strong currents that might stress them.
  • Heating: Maintain a stable temperature between 75 to 82°F (24 to 28°C) using a reliable aquarium heater.
  • Lighting: Guppies do well with moderate lighting. Live plants like Java Moss and Amazon Swords not only enhance the aesthetics but also provide hiding spots.

Water Parameters:

  • pH Level: Keep the pH between 7.0 and 8.2. Guppies are adaptable but prefer slightly alkaline water.
  • Water Hardness: Guppies prefer moderately hard water, so maintain a general hardness (GH) between 8 to 12 dGH.
  • Ammonia and Nitrites: Regularly test and ensure these levels are at zero. Frequent water changes help maintain optimal water quality.

Tank Mates

  • Community-Friendly: Guppies are peaceful and social, making them great tank mates for other non-aggressive fish like tetras, mollies, and peaceful catfish.
  • Avoid Aggressive Species: Avoid housing them with aggressive or fin-nipping fish, as guppies have flowing fins that can be tempting targets.


  • Varied Diet: Guppies are omnivores. Offer high-quality flakes, pellets, and supplement their diet with live or frozen foods like brine shrimp, daphnia, and bloodworms.
  • Feeding Frequency: Feed small portions 2-3 times a day. Ensure they consume the food within a few minutes to prevent overfeeding and water pollution.


Livebearers: Guppies are livebearers, meaning they give birth to live fry. If you have both males and females, expect them to breed naturally. Provide hiding spots like dense plants to protect fry from adult guppies, who might see them as food.

Health and Observation

Monitor their behavior daily. Changes like loss of color, unusual swimming patterns, or reduced appetite can indicate health issues. Quarantine new guppies before introducing them to the main tank to prevent the spread of diseases.

By providing a well-maintained environment, a balanced diet, and companionship in the form of compatible tank mates, you can ensure your guppy fish flourish and grace your aquarium with their lively presence. With proper care, your guppies will reward you with their vibrant colors, playful antics, and a sense of life that transforms your aquarium into a dynamic aquatic masterpiece.
