Laser Green Corydoras

Laser Green Corydoras (Corydoras sp. CW009) is one of the most visually spectacular armored catfish available. A blazing electric neon-green stripe runs the full length of the dark, almost black body — from snout to tail — creating a neon laser-beam effect that is unlike anything else available in corydoras. The 'Laser Cory' group (CW009) are among the most coveted collector corydoras in the world.

Feeding & Care Tip: Hikari Sinking Wafers make an excellent daily staple and Sera Vipachips Tropical Wafers are an excellent alternative. Supplement 2–3× per week with Hikari Frozen or Freeze-Dried Bloodworms or Hikari Frozen or Freeze-Dried Tubifex Worms to enhance the vivid electric neon-green stripe. Feed near the substrate at or after lights-out.

Native to Rio Araguaia drainage, Brazil, this species inhabits slow-moving to still, soft, slightly acidic waters with sandy substrate and leaf litter — classic South American blackwater habitat. In the aquarium, soft, slightly acidic water with tannin additions, fine sand substrate, and driftwood produces the most intense stripe coloration.

Keep in groups of at least six — this is not optional for Corydoras. In the wild these fish occur in schools of dozens to hundreds. A lone Corydoras or a group of fewer than six is a stressed fish that stays hidden, refuses food, and lives a shortened life. In a proper group they are bold, constantly active, and endlessly entertaining to watch as they forage together across the bottom of the aquarium.

Corydoras are highly sensitive to substrate quality — fine sand is strongly preferred over gravel, as rough substrates damage the delicate barbels they use to forage. Regular partial water changes and pristine water quality are essential, as all Corydoras are sensitive to nitrites and dissolved waste. Sand substrate, gentle flow, and shaded areas with driftwood or plants will keep this species at its happiest and most active.
