More Details

General info about Green gold catfish

Corydoras melanotaenia will grow up to 2.3 inches in length. They have the ability to tilt their eyes which looks like blinking. These fish are facultative air breathers, they have a highly vascularized intestine that facilitates uptake of atmospheric oxygen so they will often go to the surface for a gulp of air. Due to the ability for breathing atmospheric air, the aquarium should have a cover and the tank shouldn’t be filled to the top.

To keep this species in captivity, water pH should be between 6.0 and 8.0 and water temperature should range from 73º F and 77º F. The tank should have a sandy substrate, plants and hiding places. These fish can be kept in community aquariums and should be kept in groups.

Green gold catfish Diet & Nutrition

Corydoras melanotaenia are omnivorous. In the wild, they feed on worms, benthic crustaceans, insects, and plant matter. They will eat almost anything that sinks into the bottom of the tank, you can feed them dried, live and frozen foods.

Breeding & Spawning Green gold catfish

The female holds 2-4 eggs between her pelvic fins, where the male fertilizes them for about 30 seconds. After fertilization, the female swims to a suitable spot, where she attaches the very sticky eggs. The masked corydoras lays eggs in dense vegetation without adult protection. The pair repeats this process until about 100 eggs have been fertilized and attached.

Green gold catfish Origin

Corydoras melanotaenia can be found in South America and is found in the Meta River basin in Colombia.

Caution with Green gold catfish

Corydoras melanotaenia has hardened pectoral spines that can pierce human skin so they should be handled with care and a plastic container should be used to move them, using a net is not recommended because these spines may become entangled in the mesh.

These fish are scaleless and as such they are extremely sensitive to salt, adding salt to the tank will hurt them.

Acclimating Green gold catfish

These fish are nocturnal so they should be fed at lights out, however, after some time in the tank they may be “taught” to eat during the day.

Green gold catfish are Venomous

It is thought that at the base of each spine there are axillary glands that have mildly toxic secretions.
