The exact origin of the Red Moscow Guppy is unknown, but it is believed to have been developed in Thailand in the 1960s. It was then brought to the United States and other countries, where it quickly became a popular guppy variety.

The Moscow Red Guppy is thought to have been developed by crossbreeding a variety of guppies, including the Endler’s Guppy (Poecilia wingei) and the Koi Guppy (Poecilia reticulata var. “Koi”). The Endler’s Guppy is a small, brightly colored guppy that is native to Venezuela. The Koi Guppy is a larger guppy with a variety of color patterns, including red and white.

Tank Setup

To set up a tank for Red Guppies, you will need the following:

  • A tank that is at least 10 gallons in size.
  • A filter to keep the water clean.
  • A heater to maintain the water temperature at 65-80 degrees Fahrenheit.
  • A thermometer to monitor the water temperature.
  • A substrate, such as sand or gravel.
  • Aquarium plants and decorations.

Once you have all of your supplies, you can begin setting up your tank:

  1. Rinse the substrate well to remove any dust or debris.
  2. Add the substrate to the tank.
  3. Add the aquarium plants and decorations.
  4. Fill the tank with water.
  5. Add the filter and heater.
  6. Turn on the filter and heater.
  7. Allow the tank to cycle for at least 2 weeks before adding any fish.

Once the tank has cycled, you can add your Moscow Guppies. Start by adding a few fish at a time to give the filter time to adjust.

Water Parameters

Red Moscow Guppies prefer the following water parameters:

  • Temperature: 65-80 degrees Fahrenheit (18-27 degrees Celsius)
  • pH: 5.5-8.0
  • KH: 10-30 dKH
  • Ammonia: 0 ppm
  • Nitrite: 0 ppm
  • Nitrate: Less than 20 ppm

It is important to test the water parameters regularly to ensure that they are within the ideal range for your fish. You can use a variety of water testing kits to test the pH, KH, ammonia, nitrite, and nitrate levels in your aquarium water.

If the water parameters are outside of the ideal range, you can make adjustments by adding or removing water, using aquarium buffers, or adding salt to the water. It is important to make any adjustments gradually to avoid shocking your fish.

Tank Mates

Red Moscow Guppies are peaceful fish that can coexist with other peaceful community fish such as Half Black Guppy, Yellow Guppy, Black Moscow Guppy Blue Moscow Guppy tetras, mollies, and peaceful barbs. Avoid housing them with aggressive or fin-nipping species, as their long fins can make them targets for bullying.


Red Moscow Guppies are relatively easy to breed. To breed Moscow red Guppies, you will need a separate breeding tank. The breeding tank should be at least 10 gallons in size and should be equipped with a filter and heater. The water temperature in the breeding tank should be maintained at 75-80 degrees Fahrenheit (24-27 degrees Celsius).

Once you have set up your breeding tank, you can add a male and female Red Moscow Guppy. The male should be at least 2 months old and the female should be at least 4 months old.

The male guppy will court the female by swimming around her and displaying his fins. The female will accept the male’s advances by allowing him to fertilize her eggs.

Once the female is fertilized, she will carry the eggs for 21-30 days. During this time, it is important to feed the female a high-quality diet to ensure that she stays healthy and strong.

When the female is ready to give birth, she will hide in a secluded spot in the aquarium. The female will give birth to live fry. The fry will be very small and will need to be fed a special fry food.

Once the fry are large enough, they can be transferred to the main aquarium.

Here are some additional tips for breeding Red Moscow Guppies:

  • Make sure that the breeding tank is well-planted. The plants will provide hiding places for the fry and will help to keep the water clean.
  • Feed the female a high-quality diet during pregnancy.
  • Monitor the female for any signs of stress or illness. If the female becomes stressed or ill, she may abort the fry.
  • Remove the male from the breeding tank after the female has given birth. The male may eat the fry.

By following these tips, you can increase your chances of successfully breeding Red Moscow Guppies.


Red Moscow Guppies are omnivores and will eat a variety of foods, including flake food, freeze-dried food, and live food. It is important to feed your guppies a high-quality diet to ensure that they stay healthy and colorful.
