The Electric Green Cory is a breathtakingly vibrant freshwater fish that has captivated aquarium enthusiasts worldwide. Known for its striking green coloration and peaceful temperament, this fish makes a fantastic addition to home aquariums. Whether you are an experienced fish keeper or a beginner, learning about the Electric Green Cory’s care, diet, and habitat is essential for maintaining a thriving and healthy pet.
Appearance and Unique Features
The Electric Green Cory stands out due to its eye-catching neon green hue, making it one of the most visually appealing bottom-dwelling fish in freshwater aquariums. This species typically grows to about 2-3 inches in length, making it a great fit for small to medium-sized tanks. Its compact size, combined with its shimmering green body and dark-tipped fins, gives it a unique look that complements any tank environment.
One of the most intriguing features of the Electric Green Cory is its armored scales, which provide protection from predators. Unlike other catfish, this species lacks traditional scales and instead has bony plates covering its body. Additionally, its whisker-like barbels help it detect food along the tank’s bottom.
Natural Habitat and Origin
The Electric Green Cory is a selectively bred variant of the Corydoras species, which originates from the freshwater rivers and streams of South America, particularly in regions like Brazil, Peru, and Colombia. In the wild, Corydoras catfish are bottom dwellers that thrive in slow-moving, well-oxygenated waters with sandy or muddy substrates.
Due to their natural habitat, Electric Green Corys prefer soft, slightly acidic water with plenty of hiding spots among rocks, driftwood, and aquatic plants. Understanding their origin helps fishkeepers replicate their ideal environment in a home aquarium.

Aquarium Requirements
To keep your Electric Green Cory happy and healthy, it’s essential to set up a well-maintained aquarium that mimics its natural habitat. Here are some key tank requirements:
-
Tank Size: A minimum of 20 gallons is recommended for a small group of 4-6 fish. Since they are social creatures, they should always be kept in groups.
-
Substrate: Fine sand or smooth gravel to protect their delicate barbels.
-
Plants & Decorations: Live or artificial plants, driftwood, and caves provide necessary hiding spots.
-
Filtration: A good-quality filter is needed to maintain clean water, as Corydoras are sensitive to poor water conditions.
Water Conditions for Electric Green Cory
Maintaining stable water conditions is crucial for the health of your Electric Green Cory. The ideal parameters are:
-
Temperature: 72-78°F (22-26°C)
-
pH Level: 6.5-7.5
-
Water Hardness: 2-12 dGH
-
Ammonia & Nitrites: Keep at 0 ppm (high levels can be harmful)
Regular water changes (25-30% weekly) help prevent the buildup of harmful toxins and keep the environment stable.
Diet and Feeding Habits
The Electric Green Cory is an omnivorous bottom feeder, meaning it enjoys a variety of foods, including:
-
High-quality sinking pellets (designed for bottom feeders)
-
Frozen or live foods like bloodworms, daphnia, and brine shrimp
-
Vegetables like blanched spinach, zucchini, and peas
-
Algae wafers for additional plant-based nutrients
Feed them once or twice a day, ensuring that food sinks to the bottom where they can easily find it.
Behavior and Social Nature
Electric Green Corys are friendly, peaceful fish that do well in community tanks. They enjoy swimming in small groups and often display playful behaviors.
Best tank mates include:
-
Other Corydoras species
-
Tetras
-
Rasboras
-
Guppies
-
Gouramis
Avoid housing them with aggressive fish like cichlids or large predatory species.
Common Diseases and Health Issues
Although Electric Green Corys are hardy, they can still suffer from common fish diseases, including:
-
Ich (White Spot Disease): Small white spots on the body; treat with aquarium salt and increased temperature.
-
Fin Rot: Caused by bacterial infections; treated with antibiotics and clean water.
-
Barbel Erosion: Happens due to poor water quality or rough substrates.
Keeping the tank clean and performing regular water changes will help prevent these health problems.

Breeding Electric Green Cory
Breeding these fish is relatively easy. Here’s what you need to encourage spawning:
-
Increase water temperature slightly to 78°F
-
Feed high-protein foods like bloodworms
-
Provide hiding spots for eggs
Once eggs are laid, separate them into a breeding tank to prevent adult fish from eating them. The eggs will hatch in 3-5 days, and the fry can be fed powdered or baby brine shrimp.
Lifespan and Growth Rate
Electric Green Corys can live up to 5-8 years with proper care. Factors influencing lifespan include:
-
Water quality
-
Balanced diet
-
Stress levels
Regular care ensures they remain active and healthy for years.
