The Corydoras Green Laser (CW009), also known as the “Green Laser Cory,” is a striking and peaceful species of catfish that belongs to the Corydoras genus. Native to the Amazon Basin in South America, it is known for its vibrant green to gold iridescence, which makes it a beautiful and sought-after species in the aquarium hobby. This species is a bottom-dwelling fish, known for its peaceful nature and scavenging behavior, which helps keep the aquarium substrate clean.

Tank Requirements

  • Tank Size:
    • A minimum of 20 gallons is suitable for a small group (5–6 individuals).
    • For larger groups or community setups, 30 gallons or more is recommended.
  • Tank Setup:
    • Soft, fine gravel or sand substrate to protect their sensitive barbels.
    • Decorate with smooth rocks, driftwood, and plants to provide hiding spots and a natural environment.
    • Open swimming areas should be available, as they enjoy foraging on the bottom.
  • Lighting: Moderate to low; the reflective sheen on their scales is best shown with dimmed lighting, but they are not particularly light-sensitive.
  • Water Flow: Gentle to moderate; avoid high water movement as they prefer slow-moving waters, typical of their native habitats.

Water Parameters

  • Temperature: 72–80°F (22–27°C)
  • pH: 6.0–7.5 (slightly acidic to neutral)
  • Hardness: Soft to moderately hard (2–12 dGH)
  • Ammonia/Nitrite: 0 ppm; nitrates should be kept below 20 ppm.
  • Water Changes: Perform regular water changes of 20–30% weekly to maintain water quality and avoid ammonia buildup.

Diet

Corydoras Green Laser is an omnivore and scavenger:

  • Staple Foods:
    • High-quality sinking pellets or wafers designed for bottom-feeding fish.
  • Live/Frozen Foods:
    • Bloodworms, brine shrimp, daphnia, and blackworms.
  • Vegetables:
    • Offer blanched zucchini, spinach, or algae wafers.
  • Feeding Schedule: Feed once or twice daily, offering small portions that they can finish in a few minutes.

Behavior and Compatibility

  • Temperament:
    • Peaceful and social; Corydoras Green Laser should be kept in groups of at least 5–6 individuals to reduce stress and encourage natural behavior.
    • They are active and inquisitive, spending much of their time scavenging the substrate for food.
  • Tankmates:
    • Compatible with other peaceful species, including small tetras, livebearers, peaceful cichlids, and other Corydoras species.
    • Avoid housing with aggressive fish or very small species that could be mistaken for food.
  • Activity Level:
    • Active during the day, particularly when food is available. They will forage for food and enjoy interacting with other members of their group.

Breeding

Breeding Corydoras Green Laser is possible in a well-maintained aquarium setup:

  1. Breeding Setup:
    • A breeding tank of 20–30 gallons with soft, slightly acidic water (pH 6.0–6.5) and a temperature of 78°F is ideal.
    • Provide flat surfaces, such as broad leaves or glass, for the female to lay eggs.
  2. Spawning Behavior:
    • When the group is conditioned with high-quality food, spawning is likely to occur. The female will lay eggs on smooth surfaces, which are then fertilized by the male.
  3. Egg Care:
    • The eggs will hatch in 3–5 days, and the fry will become free-swimming within a week.
  4. Fry Care:
    • Feed the fry infusoria or liquid fry food until they are large enough to eat baby brine shrimp or finely crushed flakes.

Common Challenges

  1. Water Quality:
    • Corydoras Green Laser is sensitive to poor water quality, particularly high nitrate levels. It is essential to maintain stable water conditions with regular water changes.
  2. Barbel Damage:
    • Their sensitive barbels can be damaged by rough or sharp substrates. Ensure you provide a smooth, fine substrate (sand is ideal) to avoid injury.
  3. Overfeeding:
    • Overfeeding can result in excess food decomposing in the tank, causing water quality issues. Feed only what the fish can consume in a short period.
  4. Social Needs:
    • Corydoras Green Laser is a social species and will feel more comfortable when kept in groups. Keeping fewer than 5–6 individuals may lead to stress and reduce their overall well-being.

Interesting Facts

  • The Green Laser Cory is named for the distinctive green to gold iridescence that covers its body, particularly on its fins and tail.
  • Like other Corydoras species, they have a unique “sifting” behavior where they use their barbels to search for food in the substrate, contributing to the cleanliness of the aquarium.
  • They are a relatively recent addition to the aquarium trade and have quickly gained popularity due to their attractive appearance and peaceful nature.
  • Corydoras Green Laser is sometimes confused with the Corydoras Orange Laser (CW010), but they differ in their coloration, with the Green Laser exhibiting a more subtle greenish hue.
