Tank Setup

Lyretail guppies are relatively easy to care for, but they do require a few specific things in their tank in order to thrive. Here is a basic tank setup guide:

  • Tank size: Lyretail guppies need a tank that is at least 10 gallons in size. This will give them enough space to swim and explore.
  • Filter: A filter is essential for keeping your tank water clean and healthy. Choose a filter that is rated for a tank size that is larger than your actual tank size. This will ensure that the filter is able to keep the water clean even when there are more fish in the tank.
  • Heater: Lyretail guppies prefer warm water, so you will need a heater to keep the water temperature between 72 and 78 degrees Fahrenheit.
  • Substrate: The substrate is the material that will cover the bottom of your tank. A good substrate for lyretail guppies is a fine sand or gravel. Avoid using substrates that are too sharp or coarse, as these can damage the fish’s fins.
  • Decorations: Decorations can help to make your tank more aesthetically pleasing and can also provide hiding places for your fish. Some good decorations for lyretail guppies include live plants, rocks, and driftwood.

Lyretail guppies are susceptible to a number of diseases, including:

  • Ich: Ich is a parasitic disease that causes small white cysts to form on the fish’s body and fins. Ich is highly contagious and can be fatal if not treated promptly.
  • Fin rot: Fin rot is a bacterial infection that causes the fish’s fins to rot and disintegrate. Fin rot can be caused by poor water quality, stress, or injury.
  • Dropsy: Dropsy is a condition that causes the fish’s body to swell up with fluid. Dropsy is often a sign of a more serious underlying problem, such as organ failure or infection.

If you notice any of these signs or symptoms in your lyretail guppies, it is important to quarantine them immediately and seek treatment from a veterinarian or aquarist.

The breeding tank should be equipped with a filter and heater, but it should not have any substrate. This will make it easier to remove the fry after they are born.

The female lyretail guppy will give birth to live young after about 28 days. The fry should be removed from the breeding tank immediately after birth to prevent the adults from eating them. The fry can be raised in a separate tank until they are large enough to be added to the community tank.

  • Make sure that the male and female lyretail guppies are healthy and mature before breeding them.

  • Keep the water temperature in the breeding tank between 78 and 82 degrees Fahrenheit. This will help to increase the chances of a successful breeding.
