The Ear Guppy is one of the most visually striking and captivating types of guppies in the aquarium world. Known for their uniquely large pectoral fins that resemble ears—especially in the “Dumbo” or “Elephant Ear” variants—these guppies are a favorite among aquarists who appreciate both color and flair. Whether you’re a beginner hobbyist or a seasoned aquarist, this comprehensive guide will help you understand everything about Ear Guppies—from their origins and traits to their care, breeding, and ideal tank conditions.
What Is an Ear Guppy?
An Ear Guppy refers to a group of guppies characterized by their oversized pectoral fins (the fins located on either side of the fish, just behind the gills). These fins give the appearance of ears, hence the term “Ear Guppy.” The term is often used to describe guppies in the Dumbo Ear or Elephant Ear category.
These guppies are not just about looks. They are also peaceful, easy to care for, and add vibrant motion to any freshwater tank.
Origin and Background
Guppies, including Ear Guppies, belong to the species Poecilia reticulata. Native to South America, guppies have been bred worldwide for their color variations, tail shapes, and fin structures. The Dumbo Ear Guppy, a prominent type of Ear Guppy, was selectively bred to have enlarged pectoral fins that move like ears when swimming.
This trait likely emerged through selective breeding in Asia, particularly Thailand, where ornamental fish breeders experiment with genetics to create unique features and color morphs.
Physical Characteristics
1. Pectoral Fins
The most defining characteristic of the Ear Guppy is the massive, fan-like pectoral fins. These fins often come in contrasting or complementary colors to the body, making them even more noticeable.
2. Body Size
- Males: 1.5 – 2.5 inches
- Females: 2 – 3 inches
3. Color Variants
Ear Guppies come in a wide range of color morphs such as:
- Dumbo Ear Dragon Guppy
- Platinum Dumbo Ear Guppy
- Moscow Dumbo Ear Guppy
- Dumbo Ear Mosaic Guppy
- Blue Dumbo Ear Guppy
These combinations can include blue, red, yellow, black, platinum, and even multicolored variations.
Popular Types of Ear Guppies
1. Dumbo Ear Guppy
The most recognized type, the Dumbo Ear Guppy, has silky, oversized pectoral fins and vibrant colors. The fins often appear translucent with tinges of neon or metallic hues.
2. Platinum Dumbo Ear Guppy
This type has a shiny silver or white body with strikingly large fins. It’s a favorite for minimalist tanks and light-based aquascaping.
3. Dragon Dumbo Ear Guppy
These have dragon-scale patterns along the body and large, flowing ear-like fins. They are bold in color, often combining red, blue, and black.
Temperament and Behavior
Ear Guppies are:
- Peaceful: Ideal for community tanks.
- Active: Always swimming and showing off their fins.
- Social: They thrive in groups of their kind or with compatible species.
However, because of their large pectoral fins, Ear Guppies may not be as fast as other guppies. Avoid keeping them with fin-nippers like tiger barbs or aggressive tetras.
Tank Requirements
1. Tank Size
- Minimum: 10 gallons for a trio
- Ideal: 20+ gallons for a community setup
2. Water Conditions
- Temperature: 72°F to 82°F (22°C to 28°C)
- pH: 6.8 to 7.8
- Hardness: Moderate to hard
3. Filtration and Aeration
Use a gentle filter, such as a sponge filter, to avoid strong currents that may stress their large fins.
4. Decor and Plants
Provide:
- Live plants like Java moss or guppy grass
- Hiding spots (caves, driftwood)
- Open swimming areas
Diet and Feeding
Ear Guppies are omnivorous. For optimal health and color vibrancy, feed them a balanced diet that includes:
1. Commercial Foods
- High-quality guppy flakes
- Micro pellets
2. Protein Sources
- Brine shrimp
- Daphnia
- Bloodworms
3. Vegetable Matter
- Blanched spinach
- Spirulina-based flakes
Feed small amounts 2–3 times a day and avoid overfeeding, as it can lead to water quality issues.
Breeding Ear Guppies
Like all guppies, Ear Guppies are livebearers. This means they give birth to free-swimming fry instead of laying eggs.
1. Sexing
- Males: Smaller, more colorful, with larger pectoral fins
- Females: Bigger, rounder, duller, gravid spot near the anal fin
2. Mating Behavior
Males will pursue females to mate. A ratio of 1 male to 2–3 females is ideal to prevent stress.
3. Gestation and Fry
- Gestation: ~28 days
- Fry Count: 20–50, depending on the size and age of the female
Separate the fry or provide dense plants for hiding, as adults may eat them.
Common Health Concerns
Due to their large fins, Ear Guppies are slightly more vulnerable to injuries and infections.
Common Issues:
- Fin Rot – Caused by poor water quality or fin damage.
- Ich (White Spot Disease) – Treat with elevated temperature and medication.
- Swim Bladder Disease – Often due to overfeeding or poor diet.
Prevent illnesses by maintaining clean water, offering a varied diet, and avoiding aggressive tankmates.
