Blue Dragon Guppy: A Complete Beginners Care Guide

Guppies are one of the most popular and versatile freshwater fish for hobbyists of all levels. Among the many guppy varieties available, the Blue Dragon Guppy stands out for its striking appearance and relatively easy care requirements. In this comprehensive guide, we’ll delve into the world of Blue Dragon Guppies, covering their origin, tank setup, breeding, feeding, diseases, and more.

Origin of Blue Dragon Guppies

Blue Dragon Guppies, scientifically known as Poecilia reticulata, are a selectively bred strain of guppies originating from the tropical waters of South America. Over generations of breeding, enthusiasts have developed this stunning variety. Their name, “Blue Dragon,” is derived from the captivating blue and dragon-like patterns on their bodies, making them a prized addition to any aquarium.

Tank Setup for Blue Dragon Guppies

Creating a suitable habitat for your Blue Dragon Guppies is essential to ensure their health and vibrant appearance. Here are the key factors to consider:

Tank Size

Blue Dragon Guppies are relatively small, but they still require enough space to thrive. A tank with a minimum capacity of 10 gallons is suitable for a small group of guppies.

Water Parameters

Maintaining the right water conditions is crucial for the well-being of your Blue Dragon Guppies. Here are the recommended parameters:

ParameterIdeal Range
Temperature72-82°F (22-28°C)
Hardness (dGH)10-20 dGH
Ammonia/Nitrite0 ppm
NitrateBelow 40 ppm

Regular water testing and monitoring are essential to ensure that these parameters remain within the ideal range.

Filtration and Aeration

Blue Dragon Guppies are hardy, but they still require good water quality. An efficient filter and proper aeration will help maintain oxygen levels and remove toxins from the water.

Substrate and Decorations

To mimic their natural habitat, use fine gravel or sand as substrate and add live or silk plants for cover. Guppies appreciate hiding spots, so driftwood or decorative caves are great additions.


Moderate lighting is sufficient for Blue Dragon Guppies. Avoid excessive brightness, as it can cause stress.

Breeding Blue Dragon Guppies

Breeding guppies can be an exciting aspect of fishkeeping. Blue Dragon Guppies are prolific breeders, making the process relatively straightforward. Here’s what you need to know:

Sex Differentiation

Guppies exhibit sexual dimorphism. Males are typically smaller and more colorful, while females are larger and rounder. The males’ distinctive features include a gonopodium (a modified anal fin used for mating) and vibrant colors.

Breeding Tank

Setting up a separate breeding tank is advisable to protect the fry from being eaten by adult guppies. A small tank or breeding box within the main aquarium can serve this purpose.

Mating Process

Introduce a male and female into the breeding tank. Mating usually occurs rapidly. Female guppies are livebearers, meaning they give birth to live fry rather than laying eggs.

Pregnancy and Fry Care

Female guppies are known for their gravid spots, which darken as they become pregnant. After a gestation period of approximately 4-6 weeks, the female will give birth to a batch of fry. Ensure that there are hiding places and plants in the breeding tank where fry can seek refuge. Feed the fry with crushed flakes or specialized fry food.

Caring for Fry

Maintain proper water quality, and perform frequent water changes to ensure the survival and growth of the fry. As they grow, you can gradually introduce them to the main tank.

Feeding Blue Dragon Guppies

Feeding your Blue Dragon Guppies a balanced diet is vital for their health and coloration. Here’s what you should know about their dietary needs:

Main Diet

Blue Dragon Guppies are omnivores and will accept a variety of foods. High-quality guppy flakes or pellets should make up the staple of their diet.

Supplementary Foods

To enhance their colors and overall health, consider supplementing their diet with live or frozen foods like daphnia, brine shrimp, and bloodworms. These foods provide essential nutrients and encourage natural behaviors.

Feeding Frequency

Feed your guppies small amounts 2-3 times a day. Only provide what they can consume in a few minutes to prevent overfeeding, which can lead to water quality issues.

Common Diseases and Health Care

Maintaining the health of your Blue Dragon Guppies is crucial to enjoying their vibrant colors and active behavior. Here are some common diseases to watch out for and general health care tips:

Common Guppy Diseases

Guppies are susceptible to diseases like ich (white spot disease), fin rot, and velvet. Maintain pristine water conditions, quarantine new fish, and avoid overstocking to reduce the risk of disease.

Quarantine New Fish

Before introducing new fish into your main tank, it’s essential to quarantine them in a separate tank for a few weeks. This minimizes the risk of introducing diseases to your existing guppies.

Observation and Early Detection

Regularly observe your guppies for any signs of illness, such as clamped fins, unusual behavior, or changes in coloration. Early detection can make treatment more effective.


Blue Dragon Guppies are not only visually stunning but also relatively easy to care for, making them an excellent choice for beginner and experienced aquarists alike. By providing them with the right tank setup, proper feeding, and diligent health care, you can enjoy the beauty and vibrancy of these captivating fish in your own aquarium. Remember to pay attention to water quality, maintain suitable water parameters, and enjoy the process of breeding and raising these remarkable guppies.
