By the end, you’ll understand why this guppy variety is one of the most sought-after ornamental fish in the hobby.

What Is a Blue Leopard Guppy?

The Blue Leopard Guppy is a selectively bred strain of guppy (Poecilia reticulata) known for its blue body coloration and leopard-like black spots on its tail and fins. This pattern gives the fish a wild yet elegant look, mimicking the coat of a leopard. The intensity of the blue and the density of the spotting may vary depending on genetics, diet, and lighting.

Like all guppies, Blue Leopard Guppies belong to the Poeciliidae family and are livebearers, meaning they give birth to free-swimming fry rather than laying eggs. They are small, peaceful, and adaptable fish that thrive in community tanks.

Origin and Genetics

Blue Leopard Guppies do not occur naturally in the wild. They are the result of selective breeding by aquarists who aimed to create a strain that combines a vibrant blue body with a spotted tail pattern. This variety likely stems from crosses between blue guppies and leopard-patterned guppies, with careful selection over generations to fix the desired traits.

The term “leopard” refers specifically to the reticulated black pattern on the caudal (tail) fin and sometimes on the dorsal fin. When combined with a metallic or iridescent blue base, it creates a dazzling contrast that sets the Blue Leopard Guppy apart.

Ideal Tank Setup

Creating the right environment is key to ensuring the health and beauty of your Blue Leopard Guppy. Here’s how to set up an ideal tank:

Tank Size

• Minimum: 10 gallons for a small group (3–5 guppies)
• Recommended: 20 gallons or more for a community setup

Water Parameters

• Temperature: 72–82°F (22–28°C)
• pH: 6.8–7.8
• Hardness: 8–12 dGH
• Ammonia/Nitrite: 0 ppm
• Nitrate: < 40 ppm

Filtration and Aeration

• Use a sponge filter or gentle HOB (hang-on-back) filter.
• Ensure moderate water flow and good oxygenation.

Lighting

• Moderate lighting enhances the guppy’s blue coloration.
• Avoid excessive light that may stress the fish or promote algae growth.

Substrate and Decor

• Use fine gravel or sand.
• Include live plants like Java moss, guppy grass, or Anubias.
• Add hiding spots such as driftwood, caves, or ceramic decorations.

Diet and Feeding

Feeding your Blue Leopard Guppies a balanced and varied diet enhances their color, energy, and breeding success.

Best Foods

• High-quality flakes or pellets (specially formulated for guppies)
• Frozen or live foods like:
  • Daphnia
  • Brine shrimp
  • Bloodworms
• Vegetable matter: Blanched spinach, zucchini, or spirulina flakes

Feeding Frequency

• 2–3 times per day in small amounts
• Remove uneaten food after 3–5 minutes to maintain water quality

Behavior and Temperament

Blue Leopard Guppies are known for their peaceful, friendly nature. They do well in community tanks and are highly active swimmers.

Social Traits

• Schooling fish: Prefer to be kept in groups of 3 or more.
• Non-aggressive: Can be housed with tetras, mollies, platies, and peaceful bottom dwellers like Corydoras.

Tankmate Suggestions

• Neon Tetras
• Zebra Danios
• Harlequin Rasboras
• Cherry Shrimp (with caution)
• Snails (like Nerite or Mystery Snails)

Avoid housing them with:

• Betta fish (due to fin nipping)

Breeding Blue Leopard Guppies

Breeding guppies is simple and often occurs spontaneously in a well-maintained tank.

Mating Behavior

• Males will court females by flaring fins and performing mating dances.
• Guppies are livebearers and females can store sperm, giving birth multiple times from a single mating.

Gestation

• Lasts about 21–30 days
• Females develop a dark gravid spot near the anal fin

Fry Care

• Move pregnant females to a breeding box or separate tank before giving birth.
• Remove the female post-birth to prevent her from eating the fry.
• Feed fry crushed flakes, baby brine shrimp, or commercial fry food.

Health and Common Diseases

Though hardy, Blue Leopard Guppies can fall ill if tank conditions aren’t ideal.

Common Issues

• Ich (white spot disease): Treat with aquarium salt and raised temperatures.
• Fin rot: Caused by poor water quality; treat with antibiotics.
• Internal parasites: Look for signs like white stringy feces; treat with antiparasitic medication.

Prevention Tips
