Elegans Cory

The Elegant Corydoras (scientifically known as Gastrodermus elegans, formerly Corydoras elegans) is a small, peaceful South American catfish. Reaching just 4 to 5 cm in adulthood, these shoaling fish are prized for their playful schooling behavior, distinct mottled-stripe pattern, and low-maintenance care in community aquariums.

Profile & Appearance

• Origin: Upper Amazon River basin (Brazil, Colombia, and Peru).
• Size: 4 to 5 cm (~2 inches).
• Sexual Dimorphism:
  • Males develop bolder, more contrasting black and reticulated markings and a taller dorsal fin.
  • Females are generally larger and visibly rounder when viewed from above.
• Behavior: Highly social shoaling fish. While they spend time foraging along the bottom, they are more active in the mid-water column than many other corydoras.

Aquarium Care Requirements

Tank Size:

A minimum of 45-60 L (10 to 15 gallons) is required. They must be kept in schools of at least 6 individuals to thrive.

Water Parameters:

• Temperature: 22°C to 26°C (72°F to 79°F).
• pH: 6.0 to 7.5.
• Hardness: Soft to moderately hard water (2 to 12 dH).

Substrate:

Must be kept on fine, smooth sand or soft, rounded gravel. Their short, rounded noses and delicate barbels are highly sensitive to rough or sharp substrates.

Diet:

Omnivorous. They require high-quality sinking pellets and wafers and readily accept live or frozen foods such as daphnia, brine shrimp, and bloodworms.

Breeding

These fish have been bred in the home aquarium. Conditioning a group with a rich, live diet and performing large, slightly cooler water changes can trigger spawning. Females typically deposit small, adhesive eggs on the undersides of cleaned plant leaves or the aquarium glass.
