In terms of tank requirements, cory catfish prefer a well-maintained environment with clean water conditions. A minimum tank size of 20 gallons is recommended, with a sandy substrate to protect their delicate barbels. They appreciate having hiding places, such as caves or plants, to retreat to. It is important to maintain stable water parameters, including a temperature between 72°F and 78°F (22°C to 25°C) and a pH level between 6.0 and 7.5.

By providing the appropriate care and meeting their specific needs, cory catfish can live a long and healthy life in captivity.
