Pygmy Corydoras is a representative of the Callichthyidae family and the smallest of the bottom catfish that live in domestic ponds.
This is a schooling and peaceful fish, easy to maintain and breed. Most often they are acquired as aquarium orderlies, but tiny catfishes have their own fans.

Pygmy Corydoras Description:
The homeland of the Pygmy Corydoras is South America. These Fishes live in large schools in silted areas in the tributaries of the Madeira River and in streams with a slow flow, occasionally floating up to the surface to swallow air.
The body shape is elongated, flattened laterally, the line of the abdomen is straight. The fins are transparent, well developed, small antennae grow around the mouth.
The main color is olive with a gray tint. From the eyes to the base of the tail passes a black stripe, which ends in a spot of irregular shape.
Females are larger and fuller than males, with a rounded upper fin. In males, he is pointed.
Size of Pygmy Corydoras:
- females – 3 cm;
- males – 2−2.5 cm.
The Tankmates of the Pygmy Corydoras should be small and peaceful.

Feeding Pygmy Corydoras
In the food, Corydoras are picky and eat any living ( tubule, artemia, daphnia ) and dry (tablets for bottom fish, cereals, pellets) feed.
You can also give leaves scalded with boiling water, lettuce, dandelion or slices of fresh cucumber. The main thing is that the food is shallow, otherwise, the fish will not be able to swallow it and remain hungry.
Feed them 1 time per day in a small portion.
For the comfortable maintenance of Pygmy Corydoras, it is necessary to purchase a flock of 15 individuals. In such a company, the fish look spectacular, show their best abilities and behavioral peculiarities peculiar only to this species.
The rules for the arrangement of the aquarium are as follows:
- Aquarium – Choose from the calculation of 3 liters per individual. For a flock of 5 corydoras, a capacity of 10-15 liters is suitable. If the fish are more than 10, the volume of water has to be increased to 50 liters.
- Soil – Soft (sand or small pebbles) of a dark color, without sharp edges. Against this background, the fish will look brighter.
- Water temperature – + 22−26 degrees. It is necessary to replace 1/3 of the water weekly.
- pH is 6.5-7.5.
- GH – up to 15.
- Plants – Necessarily the presence of vegetation planted around the perimeter of the aquarium so that there is enough space for the free movement of fish. Pygmies prefer broad-leaved plants – echinodorus, cryptocoryne, anubias.
- Lighting – soft, diffused, coming from above.
- Scenery – A large number of shelters are recommended. This can be grottoes, caves, driftwood, as well as several embankments of large smooth stones, on which the fish like to relax.
- Aeration and Filtration – You must install an internal aquarium filter with aeration function or a separate filter, because catfish raise strong turbidity, rummaging at the bottom of the reservoir, and a compressor. Although the fish have intestinal respiration, additional aeration will not be superfluous.
Breeding Pygmy Corydoras
Breeding Pygmy Corydoras is somewhat more difficult than in other species. They can spawn in a common aquarium but in the absence of neighbors who like to enjoy alien caviar. In all other cases, spawning is used with a volume of 10 liters.
For breeding to be productive, it is recommended to provoke the beginning of spawning. To do this, half the volume of water is changed daily to freshwater with a lower temperature (simulate the rainy season) and feed the fish plentifully with live food.
Females and males are preferably kept separate from each other. Sexual dimorphism at this time is especially noticeable.
Spawning water is recommended soft. The temperature regime is maintained at 2-3 degrees lower than in a general aquarium.
A special substrate for spawning is laid at the bottom, plants are strengthened in it and a sponge filter is installed to prevent fry from being drawn into it.
The lighting is dim. One of the walls of the jig should be brighter. An additional glass is leaned against it, where the female will attach the eggs (it will then be easier to move it to the incubator).
In the prepared container, 2-3 females and several males are planted, which are planted immediately after spawning. The female lays up to 100 eggs, which are attached to the leaves of plants or glass.
After the end of the spawning, it is necessary to remove the whitened unfertilized and covered with fungal coating eggs. Experienced aquarists plant a certain type of shrimp in spawning, eating only infected caviar. Healthy eggs they ignore. One option is shrimp cherry.
The incubation period lasts about four days, after which the larvae hatch, which after 3-4 days begins to swim and feed on their own.
A balanced diet and proper maintenance of the pygmy corridor in a domestic pond contribute to the activity and good health of pets, who will fly around the aquarium in a cheerful flock, infecting other underwater inhabitants with their optimism.
