What does CW009 mean?

CW009 is a reference number from the Corydoras World numbering system. It identifies this specific undescribed Corydoras species from Peru. Many Corydoras are known in the hobby but have not yet received a formal scientific name — the CW system provides a standardised way to identify them.

Why is the Green Laser Cory more expensive than common Corydoras?

Green Laser Corys are wild-caught from Peru and are not mass-produced in fish farms like bronze or peppered corys. The vivid emerald stripe, limited supply, and collection costs make them a premium species. They are well worth the investment for their stunning appearance and longevity.

Can I keep just one Green Laser Cory?

Corydoras are social fish and should always be kept in groups. A single cory will be stressed and hide constantly. A group of 6 or more allows natural shoaling behaviour — they forage together, rest together, and are far more active and visible in a group.

Why Choose This Fish?

The Green Laser Cory (Corydoras sp. CW009) is widely regarded as one of the most beautiful Corydoras species in the hobby. A vivid emerald-green iridescent stripe runs from snout to tail, catching the light as the fish forages along the substrate. This laser-like stripe gives the species its common name and makes it instantly recognisable among the hundreds of known Corydoras forms.

The CW Number System

CW009 is part of the Corydoras World numbering system used for undescribed species. Many Corydoras are known to science but have not yet received formal taxonomic descriptions. The CW system gives each distinct form a reference number, allowing hobbyists and scientists to identify and discuss them accurately. CW009 was originally collected from Peru.

Substrate Matters

Like all Corydoras, the Green Laser Cory has sensitive barbels that are used to sift through the substrate for food. Fine sand is the ideal substrate — rough gravel can damage the barbels and lead to infections. A well-maintained sand bed with driftwood and live plants creates the perfect environment for these fish to display natural foraging behaviour.

Tank Mates

Peaceful with all community fish. Compatible with tetras, rasboras, and other Corydoras. Best kept in groups of 6+. See also our Skunk Corydoras, Adolfo's Corydoras, and Sterbai Corydoras.
