Emerald Green Corydoras

Emerald Corydoras, scientifically known as Corydoras splendens or Corydoras aeneus 'emerald,' are charming and popular freshwater catfish species in the aquarium hobby. With their stunning emerald green coloration and peaceful nature, they make delightful additions to community tanks.

Appearance and Behavior:
Emerald Corydoras are small, usually reaching around 2 to 2.5 inches (5 to 6 centimeters) in length. They have a distinctive emerald green coloration along their body and a light-colored underside. Like other Corydoras species, they possess two pairs of barbels around their mouth, which they use to search for food in the substrate. These catfish are sociable and prefer living in groups, so it's best to keep them in schools of at least six individuals.

Habitat and Tank Requirements:
Creating a suitable environment is crucial for the well-being of Emerald Corydoras. A tank with a capacity of at least 10 gallons is recommended for a small group of these catfish. Provide them with a soft sand substrate, as it allows them to dig and forage comfortably without damaging their barbels.

Water Parameters:
Maintaining stable water conditions is essential for the health of Emerald Corydoras. Aim for the following parameters:
- Temperature: 72°F to 78°F (22°C to 26°C)
- pH: 5.0 to 7.5
- Hardness: though they thrive in soft acidic water, Corydoras are usually able to survive in soft to moderately hard water (2 to 15 dGH)

Water Quality and Filtration:
Corydoras are sensitive to poor water quality, so regular water changes and efficient filtration are vital. A gentle filtration system is recommended to prevent strong currents that might stress the fish.

Feeding:
Emerald Corydoras are omnivorous and have a varied diet. They will eagerly accept high-quality sinking pellets, flakes, and granules formulated for bottom-dwelling fish. Supplement their diet with live or frozen foods like bloodworms, brine shrimp, and daphnia to ensure a balanced and nutritious diet.

Tankmates:
These catfish are peaceful and get along well with most community tank inhabitants. Ideal tankmates include small, non-aggressive fish like tetras, rasboras, guppies, and other peaceful species. Avoid keeping them with large or aggressive fish that might bully or prey on them.

Hiding Spots:
Emerald Corydoras appreciate hiding spots to feel secure. Provide them with plenty of cover using plants, driftwood, and caves. A well-decorated aquarium will not only enhance their well-being but also create an attractive setup.

Breeding:
Breeding Emerald Corydoras in captivity is possible with the right conditions. To encourage breeding, provide them with a separate breeding tank with slightly cooler water and frequent water changes. They may lay eggs on flat surfaces, and after spawning, remove the adults to protect the eggs and fry.

Overall, Emerald Corydoras are relatively easy to care for, making them suitable for beginners and experienced hobbyists alike. By maintaining appropriate water parameters, providing a balanced diet, and ensuring a comfortable environment, you can enjoy these delightful catfish in your community aquarium for years to come.
