To keep a small school of pygmy corydoras a tank volume starting from 10 US Gallons (40 liters) is enough. However, the larger the school is, the larger tank it requires.
In the wild the fish lives in water with the following parameters: 6.0 – 8.0 pH, water hardness 2 – 25 dGH and temperature 72°F- 78°F (22 – 26°C). You should try to maintain the same parameters in the tank.
As for the tank bottom substrate both small pebbles and large grained sand will do (the sand should be free-running and crumbly). Substrate with sharp edges may damage the catfish barbels, which makes it difficult for the fish to find food. You can also put some smooth stones on the bottom and the fish will eagerly rest on them.
Tank decorations such as snags, flower pots, coconut shells etc. will not only make the tank more appealing, but also become shelters for the fish. Tank plants will help in this respect, too and make the tank greener at the same time.
Pygmy corydoras like dim light. It’s desirable to put plants along the tank perimeter to leave free space for the fish to swim. Tank plants should have horizontal, wide leaves that are perfect for the catfish to have rest on them.
