What is a Dumbo Halfmoon Guppy?

The Dumbo Halfmoon Guppy is a selectively bred variety of guppy (Poecilia reticulata). It is named after two defining characteristics:

1. Dumbo Ears (Big Pectoral Fins): Its pectoral fins are oversized and flow like elephant ears when the guppy swims.
2. Halfmoon Tail: Its caudal fin spreads out in a wide, semi-circular fan shape that resembles a half-moon.

This combination makes the Dumbo Halfmoon Guppy a highly sought-after variety for display aquariums.

Origin and History

The Dumbo Halfmoon Guppy is not found in the wild. Instead, it is the result of years of selective breeding by guppy enthusiasts and breeders. The “Dumbo” trait originated from genetic lines focused on enhancing the pectoral fins, while the Halfmoon trait was developed through crossbreeding guppies with broader tails.

These guppies were first popularized in Asia, particularly in Thailand and Indonesia, where guppy breeding competitions often highlight such rare traits. Today, Dumbo Halfmoon Guppies are distributed worldwide and are considered premium guppy varieties.

Physical Appearance

The Dumbo Halfmoon Guppy is one of the most attractive guppy varieties. Here are its main features:

• Body Shape: Slim and streamlined, typical of guppies.
• Pectoral Fins: Enlarged “Dumbo” fins that extend outward like wings.
• Caudal Fin: A wide halfmoon tail that can reach up to 180° in spread.
• Colors: Available in multiple colorations—blue, red, purple, yellow, metallic, and multi-pattern mosaics.
• Size: Males grow up to 1.5–2 inches, while females are larger at 2–2.5 inches.

Their graceful movement makes them ideal centerpiece fish in aquariums.

Tank Requirements for Dumbo Halfmoon Guppy

Proper tank setup ensures your Dumbo Halfmoon Guppies live long, healthy lives.

Tank Size

• A minimum of 10 gallons for a small group.
• Larger tanks (20+ gallons) are recommended for breeding colonies.

Water Parameters

• Temperature: 72°F – 82°F (22°C – 28°C)
• pH: 6.8 – 7.8
• Hardness (GH): 8–12 dGH
• KH (Carbonate Hardness): 4–8

Filtration

• Use a gentle filter to avoid damaging their delicate fins. Sponge filters are ideal.

Substrate and Décor

• Fine gravel or sand as substrate.
• Plants such as guppy grass, hornwort, and java moss provide hiding spots.
• Floating plants add cover and reduce stress.

Lighting

• Moderate lighting to enhance their colors.
• LED aquarium lights with adjustable intensity are recommended.

Diet and Feeding

Dumbo Halfmoon Guppies are omnivorous, meaning they eat both plant and animal matter. A varied diet ensures vibrant colors and good health.

Recommended Foods:

• High-quality flake food (formulated for guppies).
• Pellets (small-sized sinking or floating pellets).
• Live foods: Brine shrimp, daphnia, bloodworms.
• Frozen foods: Tubifex worms, mosquito larvae.
• Vegetables: Blanched spinach, cucumber, and zucchini.

Feeding Frequency:

• Feed 2–3 times a day in small amounts that they can finish within 2 minutes.

Breeding Dumbo Halfmoon Guppy

Breeding Dumbo Halfmoon Guppies is relatively easy compared to other aquarium fish. They are livebearers, meaning females give birth to free-swimming fry rather than laying eggs.

Breeding Steps:

1. Select Healthy Pairs: Choose males and females with strong Dumbo fins and halfmoon tails.
2. Tank Setup: Use a breeding tank (10–15 gallons) with plenty of plants for fry cover.
3. Gestation Period: Females carry fry for 21–30 days.
4. Birth: A female can give birth to 20–60 fry in one batch.
5. Fry Care: Move fry to a separate tank to prevent adults from eating them. Feed them powdered fry food, baby brine shrimp, or crushed flakes.

Tip: Breeding for Dumbo and Halfmoon traits requires careful selection over multiple generations.

Common Health Issues

Like all guppies, Dumbo Halfmoon Guppies can face health problems if not cared for properly.

1. Fin Rot: Caused by poor water quality. Keep water clean and treat with antibacterial medication.
2. Ich (White Spot Disease): Treat with aquarium salt and Ich medication.
3. Swim Bladder Disorder: Avoid overfeeding and provide a balanced diet.
4. Fungus Infections: Isolate infected fish and treat with antifungal medication.

Prevention Tip: Maintain excellent water quality and feed a varied diet.
