Corydoras aeneus is one of the most common Corydoras species available to hobbyists and many different variants and color forms are available. The Bronze Cory is the "natural" form and has an iridescent brown-green body.

The small catfish from the genus Corydoras are often referred to collectively as the "Cory Cats". This genus has well over 100 members, all coming from South America and ranging in size from under 1 inch to up to around 3 inches in length as adults.

Cory cats are schooling fish, and should be kept in groups of at least 3-5 fish or more. Temperature should be monitored closely as Cory cats get easily stressed by cooler temperatures. They are also sensitive to stress and water quality. Monitor conditions closely as improper pH or high ammonia, nitrite or nitrate levels especially can be very harmful to Cory cats.

Corydoras catfish are found in some environments with low oxygen levels. To cope with this, they have adapted to take gulps of atmospheric air, absorbing the oxygen through their intestines and discharging the rest. It is normal to see them occasionally swim to the top, take a "breath" from the surface and return to the bottom. If they are doing this very often, however, check the water quality and make sure the oxygen isn't being depleted as a result of high temperature, high ammonia or nitrites, poor circulation or another condition.

Corydoras are peaceful and can be kept in most community and planted aquariums with fish like tetras, danios, rasboras, livebearers and rainbows. Provide broad-leaf plants and crevices under rocks or other ornaments for hiding places as well as some open areas for swimming room. Avoid substrate with sharp or jagged edges that can irritate and damage their undersides and barbels; fine or sandy substrates are best. They accept flake and small pellet foods as well as tablets, live or frozen worms, and brine shrimp.

They make great bottom feeders


I love these catfish because they are extremely cute [in my opinion] and clean the tank well.My bronze cory cats get along great with my albino,panda and peppered cory cats.Anyway if you need a hardy,active bottom feeder,these guys are the choice for you

Almost our favorite


We refer to them as the VW parking lot when they are resting, They can be very active and comical to watch. Can be bred easily so we lost track of how old they get. Friendly to all other tank mates. Keep a good clean, neutral tank and breed now and then and you will never run out. Keep at least five. Very social.

Great little community Fish


Above all these little guys are geat little bottom feeders.I ordered five and they act like a little school going everywhere together. They are very peaceful and intermingle with my peppered corys and my albino corys all the time with no problems.
