Tank Setup

Creating a suitable habitat for your tropical fish Purple Dragon Mosaic Guppies is essential for their well-being. Here are some key considerations for setting up their tank:

Tank Size

A 10-gallon tank is sufficient for a small group of Purple Dragon Mosaic Guppies. However, if you plan to keep a larger community or intend to breed them, a 20-gallon tank or more is recommended. Providing adequate space ensures a healthier and more harmonious environment for your guppies.

Water Parameters

Maintaining the right water conditions is crucial. Purple Dragon Mosaic Guppies thrive in slightly alkaline water with a pH level of 7.0 to 7.2. The water temperature should be kept between 72°F to 82°F (22°C to 28°C). Regular water testing is essential to ensure these parameters remain stable.

Filtration and Aeration

Guppies appreciate a gentle water flow, so using a sponge filter or a low-flow filter is recommended. Adequate aeration is essential to maintain oxygen levels in the water. Guppies are known to swim near the surface to breathe, so ensure the water is well-oxygenated.

Substrate and Decor

A fine gravel substrate is ideal for guppy tanks. You can add live or artificial plants, driftwood, and caves to create hiding spots and enhance the aesthetics of the aquarium. Ensure that there are no sharp objects that could damage their delicate fins.


Moderate to bright lighting is suitable for Purple Dragon Mosaic Guppy tanks. This lighting level encourages the growth of live plants, which can help maintain water quality and provide a more natural environment for your fish.


Regular water changes, usually around 20% every two weeks, are necessary to keep water quality in check. Vacuum the substrate to remove debris, and ensure the filter is cleaned regularly to prevent the accumulation of harmful substances.

Breeding Purple Dragon Mosaic Guppies

Breeding Purple Dragon Mosaic Guppies can be an enjoyable and rewarding experience, given their striking appearance. Here’s how you can go about it:

Selecting Breeding Pairs

Start by identifying a male and female with the desired coloration and patterns. The male’s vibrant colors and mosaic pattern are particularly important, as these traits are passed on to their offspring.

Breeding Tank

To increase the chances of successful breeding, it’s advisable to set up a separate breeding tank. This tank should be well-planted, providing ample hiding places for the fry (baby guppies). You can use a smaller tank, around 5 gallons, for this purpose.


Prior to introducing the breeding pair into the breeding tank, condition them with a high-quality diet. Live or frozen foods, such as brine shrimp or daphnia, can enhance their reproductive readiness.

Introducing the Pair

Once the fish are well-conditioned, place the male and female in the breeding tank. The female will give birth to live fry, which should be protected from potential predators, including the parents.

Caring for Fry

After giving birth, it’s essential to separate the fry from the adults, as adult guppies may consume their offspring. You can transfer the fry to a separate rearing tank with gentle filtration to maintain water quality. Feed them with finely crushed flake food or specially designed fry food to support their growth.


Selecting suitable tankmates for your Purple Dragon Mosaic Guppies is crucial for their well-being. Here are some compatible choices:

Avoid aggressive or fin-nipping species like some barbs or cichlids, as they may stress or harm your guppies.


Proper nutrition is key to maintaining the vibrant colors and overall health of your Purple Dragon Mosaic Guppies. These fish are omnivores, and their diet should be varied. Here are some feeding guidelines:

  • High-Quality Flake Food: A staple diet of high-quality guppy flakes is essential. Look for foods formulated for guppies to meet their specific nutritional needs.
  • Live and Frozen Foods: Supplement their diet with live or frozen foods such as brine shrimp, daphnia, and bloodworms. These treats will enhance their coloration and provide essential nutrients.
  • Vegetables: Occasional offerings of blanched vegetables like spinach or zucchini can provide fiber and variety in their diet.

Feed your guppies small portions two to three times a day, ensuring they consume all the food within a couple of minutes. Overfeeding can lead to water quality issues, so be mindful of portion sizes.

Common Diseases

Like all aquarium fish, Purple Dragon Mosaic Guppies can be susceptible to diseases. Here are some common ailments to watch out for:

  • Ich (White Spot Disease): This parasitic disease presents as small white spots on the fish’s body, fins, and gills.
  • Fin Rot: Bacterial infections can cause fraying and discoloration of the fins.
  • Dropsy: This condition is characterized by the swelling of the fish’s body due to internal issues.

To prevent diseases, maintain good water quality, and avoid introducing sick fish into your tank. Quarantining new additions for a few weeks can also help prevent the spread of diseases.


Purple Dragon Mosaic Guppies typically have a lifespan of 2 to 3 years when provided with proper care. A healthy diet, suitable tank conditions, and prompt disease management can contribute to a longer and happier life for these colorful fish.
