Corydoras griseus

The Corydoras griseus inhabit the Potaro River, a major tributary of the Essequibo River in Guyana, South America. It should be said that these catfish are very similar to several species of corydoras, which were discovered later and at this time they have not yet been described and given the code names C040 and C073.

Corydoras griseus has a light grey body colour, with a lighter abdomen than its back. The tail plumage and fins are translucent, colourless. On the head, through the eyes is a black broad stripe. Females are generally larger than males and have a more rounded abdomen. The maximum size of the fish is about 5 cm. The fish live a bottom-dwelling lifestyle.

Corydoras griseus

The Corydoras griseus is a peace-loving, undemanding and undemanding fish. Keep these catfish is recommended in a small group of 4-6 fish. This number of fish requires an aquarium volume of 80 liters.

Use coarse-grained river sand or fine sandy gravel as substrate. Other decoration depends largely on personal preference, but for personal safety should be provided in an aquarium shelter in the form of snags and bushes of plants. Perhaps the content corridor gray in the general aquarium with other small peace-loving fish occupying the upper and middle layers of water.

Water parameters: temperature 20-26° C, hardness dH 2-12°, acidity pH 6,0-7,5. Requires filtration, aeration and a weekly change of ¼ of the aquarium water with fresh water.

Bright to medium light.

The Corydoras griseus is an omnivore. These fish eat almost any food that falls to the bottom, from the surface of the water, they do not take food. The fish are fed with live and frozen artemia, daphnia, bloodworms, flakes and pellets. The food is given in the evening. Under no circumstances should corydoras survive on the remains of food from other aquarium inhabitants.


For successful breeding Corydoras griseus need that the aquarium per 1 female there were 2-3 males. When the abdomen of females gets noticeably fatter, make a large water changes (50-70%) of the cooler and increase aeration of water. Water changes should be made daily until the females spawn.

Females spawn on aquarium panes, in small-leaved plants or on the inside walls of shelters. Once spawning is complete, producers should be removed, and the water in the aquarium with eggs intensively aerated.

Many aquarists add a few drops of methylene blue or 1-2 alder cones in the water to prevent the development of fungus in the eggs.

The eggs incubate for 3-4 days. The hatched fry feed on the substances in their yolk sacs for the first few days of their lives, after which they begin to eat Artemia nauplii.

Water quality should be monitored to reduce the mortality of the fry. It has been observed that fry are less susceptible to disease if they are kept on a thin layer of sand rather than the bare bottom.

The life expectancy of Corydoras griseus in an aquarium is about 4 years.
