One Tank. One System. Healthy Livestock.
Corydoras are among the most beloved freshwater aquarium fish in the world. Known for their peaceful nature, playful group behaviour, and constant activity along the bottom of the tank, Corydoras catfish are perfect companions for planted aquariums and community setups.
These small armored catfish originate from South America and naturally live in large groups in slow-moving rivers and flooded forest habitats. In aquariums, they thrive when kept in groups and are constantly exploring the substrate in search of food. Their gentle personality makes them excellent tank mates for tetra species, rasboras, dwarf cichlids, and other peaceful fish.
Unlike many bottom fish, Corydoras should always be kept in groups. When maintained in proper schools, they display natural behaviours such as synchronized swimming, playful exploration, and social interaction within the group.
Corydoras naturally sift through soft sand substrates while searching for food. Fine sand or smooth substrate is highly recommended to protect their sensitive barbels. In planted aquariums with driftwood, leaf litter, and gentle filtration, Corydoras often display their most natural behaviours.
Ideal tank mates include small tetra species, rasboras, pencilfish, and other peaceful community fish. Because of their calm nature, they are commonly used as bottom dwellers in aquascaped planted tanks.
At Topick Aquarium, all Corydoras are carefully conditioned and stabilized before being offered for sale. Our systems follow a strict one-tank-one-system approach to reduce cross contamination and maintain stable microbial environments. Fish are gradually adapted to tap water parameters so they transition smoothly into most home aquariums.
This process significantly improves long-term survival and ensures customers receive healthy, stable fish ready for planted or community aquariums.
