About this item
The Gold Green Cory Catfish (Corydoras melanotaenia) is a beautiful and peaceful bottom-dwelling catfish admired for its metallic green to golden sheen along the body. This species belongs to the popular Corydoras family and is well known for its active schooling behavior and gentle temperament, making it an excellent addition to community aquariums.
Native to South America, Gold Green Corydoras inhabit slow-moving rivers and tributaries with sandy substrates and dense vegetation. In the aquarium, they thrive in well-planted tanks with soft substrate and stable water conditions.
Like most Corydoras species, they are social fish that feel most comfortable when kept in groups, often seen exploring the aquarium floor together in search of food.

Beautiful addition to my reef!
The fish arrived in perfect condition. Packaging was triple insulated with heat packs. Acclimation was smooth and it was eating frozen mysis within 2 hours of introduction. AquaEditorial never disappoints.
Great value for the price
Exactly as described. Fast shipping and very well packed.
Good but picky eater
Beautiful specimen, arrived healthy. Takes a while to adjust to new food but eventually started eating pellets. Great addition to my South American cichlid tank.
FAQs
What temperature should I keep the tank at for this fish?
Great question! We recommend maintaining a water temperature of 82–86°F (28–30°C). Discus are tropical fish and thrive in warm, stable water conditions. A reliable heater with a thermostat is essential.
Can I keep this with other fish in a community tank?
Yes! Discus are peaceful and social. They do best with calm tank mates like Cardinal Tetras, Rummy Nose Tetras, and Corydoras Catfish. Avoid aggressive or fast-moving fish that may stress them.
What size tank do I need for a small group?
We recommend a minimum of 55 gallons for a small group of discus. They need spacious aquariums with open swimming areas, live plants, driftwood, and gentle filtration.
What should I feed them?
Discus are omnivores and benefit from a varied diet. We recommend high-quality discus pellets, frozen bloodworms, brine shrimp, and beef heart mixes. A varied diet helps maintain vibrant coloration.
Do you guarantee live arrival?
Absolutely! All live fish are shipped with our 100% Live Arrival Guarantee. If there are any issues upon delivery, contact us within 2 hours with photos and we'll make it right.
