1. What is a Blue Tail Guppy?
The Blue Tail Guppy is a selectively bred variety of Poecilia reticulata, known for its vivid blue tail and translucent or similarly colored body. These guppies are not found in the wild; they are the product of years of selective breeding to enhance and stabilize their bright blue tail color.
The blue tail can range from light sky blue to deep royal blue, sometimes showing iridescence or even subtle patterns such as spots or lines. Some Blue Tail Guppies also have matching blue dorsal fins, while others may have different hues across their bodies, adding to their unique appeal.
2. Origin and Background
Guppies are native to parts of South America and the Caribbean, including countries like Venezuela, Trinidad, and Barbados. However, the Blue Tail Guppy is a result of domestic breeding efforts by aquarists around the world, particularly in Asia and Europe, where guppy shows and competitions are popular.
The primary goal in creating the Blue Tail Guppy was to develop a strain with a vibrant, uniform blue tail that would hold its color throughout generations. Today, this variety is considered both a show-quality fish and a popular choice for home aquariums.
3. Physical Appearance
Blue Tail Guppies are small, usually growing to 1.5 to 2 inches (4 to 5 cm) in length. They have a streamlined body and a prominent fan-shaped tail that is the centerpiece of their appearance. Here’s what sets them apart:
- Tail Color: A rich blue color, often covering the entire tail fin. It may appear electric or metallic under aquarium lighting.
- Body: The body may be a lighter blue, silver, gray, or transparent. Some strains show iridescent scales.
- Fins: In many cases, the dorsal and anal fins match the tail color for a balanced aesthetic.
- Sexual Dimorphism: Males are smaller, more colorful, and have larger fins, while females are larger and duller with shorter tails.
4. Lifespan and Behavior
Blue Tail Guppies have a typical lifespan of 1.5 to 3 years, depending on their environment and care. They are peaceful, active, and social fish that spend most of their time swimming near the surface and middle layers of the tank.
These guppies thrive in groups and do best when kept in male-to-female ratios of 1:2 or 1:3 to reduce mating stress on the females. They’re also curious and interactive, often approaching the glass when someone nears the tank.
5. Tank Requirements
To ensure a healthy environment for your Blue Tail Guppies, it’s essential to set up a tank that meets their basic needs.
Ideal Tank Size
- Minimum of 10 gallons for a small group
- Larger tanks (20+ gallons) are preferred for mixed communities or breeding setups
Water Parameters
- Temperature: 74°F to 82°F (23°C to 28°C)
- pH: 6.8 to 7.8
- Hardness: Moderate to hard (8–12 dGH)
- Ammonia/Nitrite: 0 ppm
- Nitrate: < 40 ppm
Filtration and Aeration
- Use a sponge filter or hang-on-back filter with gentle flow to protect fins
- Ensure good oxygenation with an air stone if needed
Lighting
- Moderate lighting to enhance their blue coloration
- Avoid overly bright light, which may stress the fish
Substrate and Decor
- Use dark substrate to make the blue colors pop
- Add live plants (like guppy grass, java moss, hornwort)
- Include hiding places using driftwood or decorations
6. Diet and Nutrition
Blue Tail Guppies are omnivores and thrive on a varied diet. A balanced and nutrient-rich feeding routine helps maintain their color vibrancy and health.
Recommended Diet
- High-quality flake or pellet food formulated for tropical fish
- Live or frozen foods like:
- Brine shrimp
- Daphnia
- Bloodworms
- Mosquito larvae
- Vegetables: Blanched spinach, cucumber, or peas (occasional)
Feeding Tips
- Feed small amounts 2–3 times daily
- Remove uneaten food to maintain water quality
- Vary the diet weekly to prevent nutrient deficiencies
7. Tank Mates
Blue Tail Guppies are peaceful and get along well with a variety of other community fish. Avoid aggressive or fin-nipping species.
Ideal Tank Mates
- Other guppies
- Corydoras catfish
- Neon or ember tetras
- Harlequin rasboras
- Mollies
- Platies
- Snails and shrimp (like nerite snails or Amano shrimp)
Avoid These
- Tiger barbs
- Large cichlids
- Bettas (in some cases)
8. Breeding Blue Tail Guppies
Breeding guppies is straightforward, and Blue Tail Guppies are livebearers, meaning they give birth to free-swimming fry rather than laying eggs.
Breeding Setup
- A separate breeding tank (10–20 gallons) is recommended
- Maintain optimal water quality and temperature (around 78°F)
- Use dense floating plants or breeding boxes for fry protection
Mating Process
- Males court females with fluttering displays
- Gestation period: 21–30 days
- Female gives birth to 20–50 fry per batch
Fry Care
- Feed fry with infusoria, crushed flakes, or baby brine shrimp
- Separate from adults to prevent predation
- Grow-out tanks help with faster development and color formation
9. Common Health Issues
Like all fish, Blue Tail Guppies can fall ill if their water conditions or diet are not properly managed.
Common Diseases
- Ich (white spot disease): Treated with temperature rise and medication
- Fin rot: Caused by poor water quality; treat with antibiotics
- Swim bladder disorder: Often linked to overfeeding or constipation
- Fungal infections: Appears as cottony patches
Prevention Tips
- Regular water changes (25–30% weekly)
- Quarantine new fish
- Avoid overfeeding
- Maintain clean substrate and filters
