Jumbo green cory catfish are found in South America from Colombia and Trinidad in the north as far south as the Río de la Plata drainage at the border of Uruguay and Argentina. Jumbo Bronze corys mostly inhabit slow-moving rivers and streams and prefer areas with shallow, muddy water, however, they have also been found in fast-flowing rivers.
Colors and Markings
Small, active, and peaceful, the green cory catfish is just a color variation of the same species known as the green cory. In addition to color variations of green, bronze, albino, and even black, this species is one of many fish that is sometimes injected with dye to enhance its color.1 Do not purchase any fish specimens that are suspected of being color-dyed as this causes long-term health problems for the fish. It is also wise to avoid any that have damaged barbels, or those having a sunken belly, which indicates inadequate feeding and susceptibility to disease.
Like all corydoras, this species is armored with overlapping scales known as plates or scutes. Their fins possess a leading spine, which can be locked in place to make it difficult for larger fish to swallow them. This spine can also make netting them difficult, and care should be taken when doing so. In the home aquarium, corys are prized for being charmingly expressive.
Jumbo green cory catfish are schooling fish. Keep them in groups of at least five. Cory catfish tankmates may include most community tank species as long as they are non-aggressive and friendly in nature. Otocinclus catfish, tetras, swordtails, and other corys can be a good fit. Avoid putting cords in the same tank with Oscars, Texas cichlids, or Jack Dempseys. These species can injure corys or may try to eat them.
