Corydoras leopardus (Corydoras leopardus ) – a small representative of the cuirass family with characteristic spots on the body resembling a leopard pattern.


Kiryski leopards are found in Peru, Ecuador and Brazil. They live in rivers, streams and tributaries.

Characteristics and disposition

They reach a length of 7.5 cm. The body is covered with dark spots.

The sex of the cuirass is best distinguished from above. Females are usually fuller and wider than males. The leopard cuirass has a characteristically elongated snout, which makes it easier to distinguish it from very similar cuirasses such as the cuirass of the julii ( C. julii ) and the cuirass of the trumpet ( C. trilineatus ).

A very calm species in which no aggressive behavior towards other fish has been observed. However, they can eat their roe or fry. In nature, they swim in large shoals, penetrating the bottom in search of food. A minimum of 6 individuals should be kept in the aquarium. They are more active and bolder in the group.

Nutrition and feeding

Accepts most drowning dry foods as well as small live or frozen foods.


A 60-70 l tank with a soft, preferably sandy substrate will be suitable for a small group of cuiras. Hiding places made of roots and smooth stones as well as broad-leaved plants will be welcome in the aquarium. Kiryski like well-oxygenated water. Sub-gravel filtration and surfaces with sharp edges, e.g.

basalt, should be avoided. Kiryski fits into any general aquarium in which there will be no large and aggressive fish. They can be kept with small cyprinids, small fish , small cichlids ( Cichlid ramireza ) . They feel best in the company of other kirysków.


A spawning aquarium with dimensions of at least 45x30x30 cm.

At the bottom we pour sand, substrate or leave it clean. It is also worth adding some small-leaved vegetation, e.g. java moss. Kiryski is transferred to the breeding aquarium and fed abundantly with live or frozen food. There should be two males for each female.

When the females appear fuller, make a large water change (50% -70%) 5 ° C cooler than that in the tank and increase the aeration. We repeat the activity for several days. During spawning, cuiras are more agitated, e.g. they swim continuously up, down and along the front glass of the tank. The males start chasing the females and the act begins.

The female touches the male’s anus and swallows his semen. It then releases the eggs onto its own anal fins and fertilizes them. Roe sticks to plants, windows or other elements. After spawning is finished, the adults are separated. By breeding cuiras in a group, we can get even several hundred eggs.

Hatching takes about 3 days. We feed the fry with small foods, e.g. brine shrimp larvae, tubers.
