The tail fin is often adorned with intricate patterns and colors, adding to the fish’s overall beauty.

  • Compatibility: Lyretail Guppy Males can coexist peacefully with other peaceful fish species, such as tetras, rasboras, and corydoras catfish. However, it’s important to avoid housing them with aggressive or fin-nipping fish, as they may become stressed or harassed.

Creating the Ideal Habitat for Lyretail Guppy Males

To ensure the well-being and vitality of your Lyretail Guppy Males, it’s crucial to create a suitable habitat that meets their specific needs and preferences.

Tank Size and Setup:

  • Tank Size: A 10-gallon tank is the minimum recommended size for a small group of Lyretail Guppy Males. However, a larger tank, such as a 20-gallon or 30-gallon tank, is ideal to provide ample swimming space and prevent overcrowding.
  • Substrate: Choose a fine-grained substrate, such as sand or gravel, that won’t irritate the delicate fins of your Lyretail Guppies. Avoid sharp or rough substrates that could damage their fins.
  • Plants and Decorations: Provide plenty of live plants and hiding places, such as driftwood and rocks, to create a natural and stimulating environment for your fish. Live plants also help maintain water quality by absorbing nitrates and providing oxygen.

Water Parameters:

  • Temperature: Lyretail Guppy Males thrive in warm waters, with an ideal temperature range of 72-82°F (22-28°C). Use a reliable aquarium heater to maintain a stable temperature within this range.
  • pH: Aim for a pH level between 6.8 and 7.8, as Lyretail Guppies prefer slightly alkaline water. Monitor the pH level regularly using a test kit and adjust it as needed.
  • Hardness: Lyretail Guppies can tolerate a wide range of water hardness, but they prefer slightly hard water with a GH (general hardness) of 10-20 dGH.

Filtration and Maintenance:

  • Filtration: Invest in a high-quality filter system that can efficiently remove waste and debris from the water. A sponge filter or a hang-on-back filter is a good choice for Lyretail Guppy tanks.
  • Water Changes: Perform regular water changes of approximately 20-30% every week to maintain water quality and prevent the buildup of harmful toxins. Use a gravel vacuum to remove debris from the substrate during water changes.

Feeding and Nutrition for Lyretail Guppy Males

A balanced and nutritious diet is essential for the health and vitality of your Lyretail Guppy Males.


  • Variety: Offer a varied diet that includes high-quality flake food, live food, and frozen food. Live food, such as brine shrimp and daphnia, is a particular favorite among Lyretail Guppies and provides essential nutrients.
  • Frequency: Feed your Lyretail Guppy Males several small meals throughout the day, rather than one large meal. This helps prevent overfeeding and ensures they receive a constant supply of nutrients.


  • Vitamins and Minerals: Consider adding vitamin and mineral supplements to your Lyretail Guppy’s diet to ensure they are getting all the essential nutrients they need for optimal health and coloration.

Breeding Lyretail Guppy Males

Lyretail Guppy Males are relatively easy to breed in captivity, making them a popular choice for beginner and experienced aquarists alike.

Breeding Setup:

  • Separate Breeding Tank: Set up a separate breeding tank to prevent the fry from being eaten by the adult fish. A 10-gallon tank is a suitable size for breeding Lyretail Guppies.
  • Water Parameters: Maintain the same water parameters in the breeding tank as in the main tank to ensure a stable and suitable environment for the fry.
  • Plants and Hiding Places: Provide plenty of plants and hiding places in the breeding tank to give the fry a sense of security and protection.

Breeding Process:

  • Introduce the Breeding Pair: Introduce a single Lyretail Guppy Male and one or two Lyretail Guppy Females into the breeding tank. The male will begin courting the females by displaying his vibrant colors and flowing tail fin.
  • Mating: When the female is ready to mate, she will allow the male to fertilize her eggs internally. The gestation period for Lyretail Guppies is approximately 21-30 days.
  • Fry Care: Once the female gives birth, remove the adult fish from the breeding tank to prevent them from eating the fry. Feed the fry with finely crushed flake food or live food suitable for their size.
