Guppies are among the most popular freshwater fish in the aquarium hobby, admired for their colors, adaptability, and ease of breeding. One of the most fascinating and unique strains of guppies is the Dumbo Big Ear Guppy. Known for their oversized pectoral fins resembling elephant ears, these guppies bring both elegance and charm to any aquarium setup.
The Dumbo Big Ear Guppy is not just another guppy strain; it represents years of selective breeding to achieve those signature wide pectoral fins that flow gracefully as the fish swims. Their distinct appearance makes them a centerpiece fish in community tanks and a favorite among guppy enthusiasts and breeders.
In this detailed guide, we’ll cover everything you need to know about Dumbo Big Ear Guppies, including their history, appearance, behavior, tank requirements, diet, breeding, and care tips.
Origin and History of Dumbo Big Ear Guppies
Guppies (Poecilia reticulata) are native to South America, particularly regions in Venezuela, Brazil, and Guyana. Over time, guppies were introduced to many parts of the world due to their ability to control mosquito populations.
The Dumbo Big Ear Guppy strain is not naturally found in the wild. Instead, it is the result of selective breeding by aquarists who sought to create a guppy with larger, more dramatic pectoral fins. The name “Dumbo” comes from the Disney elephant character known for his oversized ears.
Breeders achieved this trait through multiple generations of careful pairing, often crossing guppies with naturally larger fins until the big pectoral “ears” became a stable genetic feature. Today, Dumbo Big Ear Guppies come in various colors and tail patterns, including dragon, mosaic, lace, and albino varieties.
Appearance and Characteristics
Signature “Big Ears”
The most striking feature of the Dumbo Big Ear Guppy is its large pectoral fins, which can extend outward like wings. These fins create a flowing, elegant movement when the fish swims.

- Full Red Dumbo Ear Guppy
- Blue Dumbo Ear Guppy
- Dragon Dumbo Big Ear Guppy
- Mosaic Dumbo Ear Guppy
- Platinum White Dumbo Ear Guppy
Each strain combines the oversized pectoral fins with unique color morphs, making them highly sought after in the aquarium trade.
Size
- Males: Usually grow up to 1.5–2 inches.
- Females: Larger, often reaching 2–2.5 inches.
Lifespan
With proper care, Dumbo Big Ear Guppies can live 2 to 3 years, though some may live longer in optimal conditions.
Behavior and Temperament
Like most guppies, Dumbo Big Ear Guppies are peaceful, social, and active. They thrive in community aquariums and get along well with other small, non-aggressive fish.
Key behavior traits include:
- Schooling behavior: Guppies enjoy swimming in groups, making them more confident and less stressed.
- Playful nature: Males often display their fins to females during courtship.
- Curiosity: They explore their tank environment constantly.
Because of their peaceful temperament, Dumbo Big Ear Guppies make excellent choices for beginner aquarists.
Tank Requirements for Dumbo Big Ear Guppies
Tank Size
A minimum of 10 gallons is recommended for a small group, though larger tanks (20 gallons or more) provide better swimming space and stability.
Water Parameters
- Temperature: 72°F to 82°F (22°C–28°C)
- pH: 6.8 to 7.8
- Hardness: 8–12 dGH
- Ammonia/Nitrite: 0 ppm (very sensitive to toxins)
Filtration and Aeration
Since guppies produce waste, a gentle filter is necessary to maintain water quality. Sponge filters or hang-on-back filters are ideal. Avoid strong currents, as their big pectoral fins can make swimming in fast water tiring.
Tank Decorations and Plants
- Use live plants like Java moss, Hornwort, and Anubias to provide hiding spots.
- Keep open swimming areas for their active behavior.
- Fine gravel or sand substrate works best for planted setups.
Diet and Feeding
Dumbo Big Ear Guppies are omnivorous and need a balanced diet for vibrant coloration and fin health.
Recommended Foods:
- High-quality flakes or micro pellets (staple diet)
- Frozen or live foods: Brine shrimp, daphnia, bloodworms, and mosquito larvae
- Vegetable matter: Spirulina, blanched spinach, or zucchini slices
Feed them small portions 2–3 times a day, ensuring they eat within 2 minutes. Overfeeding can lead to poor water quality and health issues.
Breeding Dumbo Big Ear Guppies
Breeding Behavior
Like all guppies, Dumbo Big Ear Guppies are livebearers, meaning females give birth to live fry instead of laying eggs. Breeding them is relatively easy.
Breeding Setup
- Use a separate breeding tank (10–15 gallons) with plants or breeding grass for fry to hide.
- Maintain warm water (around 78°F) to encourage breeding.
- Provide high-quality food to conditioning pairs.
Gestation and Fry Care
- Female guppies have a gestation period of about 21–30 days.
- They can give birth to 20–60 fry at a time.
- Fry should be separated from adults to prevent predation.
- Feed fry with powdered flakes, infusoria, or baby brine shrimp for fast growth.
Health and Common Issues
Common Diseases
- Ich (White Spot Disease) – Caused by parasites; treat with temperature increase and medication.
- Fin Rot – Results from poor water quality; prevent with regular tank maintenance.
- Velvet Disease – Caused by parasites, appears as a gold dust coating.
- Swim Bladder Disorder – Can occur due to overfeeding or genetic issues.
Prevention Tips
- Perform regular water changes (25–30% weekly).
- Avoid overcrowding.
- Quarantine new fish before introducing them.
- Provide a balanced diet with vitamins and proteins.
