Care and Environment
Caring for the Mini Cory involves creating an environment that mirrors its natural habitat. A minimum tank size of 70 liters is recommended to provide ample space for a small group, as these fish are social and prefer to be kept in groups of at least six. The tank should be well-planted with plenty of hiding spots, using smooth sand or round gravel as substrate to protect their sensitive barbels.
Maintaining water quality is crucial. The ideal water parameters include a temperature range of 22–26°C, a pH between 6.0 and 8.0, and water hardness from 2 to 25 dGH. Regular water changes and efficient filtration are essential to keep the environment clean and stable.
Lighting should be moderate to mimic their natural conditions. When it comes to feeding, Mini Corys are omnivorous. They accept high-quality flakes and catfish pellets as staples, supplemented with live or frozen foods like brine shrimp and bloodworms to ensure a balanced diet.
