Pygmy Cory - Corydora Pygmaeus

The pygmy corydoras or pygmy catfish is a tropical and freshwater fish belonging to the subfamily Corydoradinae.

Pygmy Cory (Corydoras pygmaeus) is a delightful miniature catfish known for its small size and social nature. These active and peaceful fish are perfect for nano and community tanks, where they add charm with their constant activity and schooling behaviour. Ideal for aquarists of all levels, Pygmy Corys are hardy and easy to care for when kept in the right environment.

Caring for Pygmy Corys

Pygmy Corys adapt well to tanks as small as 20 liters, ideal for nano aquariums. They favor soft, sandy substrates to safeguard their sensitive barbels and benefit from environments rich in live plants, driftwood, and ample open swimming areas. Optimal water conditions include temperatures between 22°C and 26°C and a pH of 6.5 to 7.5. Consistent water changes and gentle filtration are essential to maintain a clean, low-stress habitat.

Ideal Tank Mates for a Pygmy Cory

Pygmy Corydoras are peaceful and thrive best when kept in groups of six or more to promote their natural schooling instincts. They are compatible with other small, gentle species like Ember Tetras, Chili Rasboras, and shrimp. Due to their diminutive size, it is important to avoid pairing them with larger or aggressive fish to prevent stress or harm.

Feeding

Pygmy Corydoras are omnivores that thrive on a diverse diet. Their main food should be premium sinking pellets or micro-pellets, complemented by live or frozen treats such as daphnia, baby brine shrimp, or bloodworms. Supplementing with blanched vegetables like zucchini or cucumber helps maintain a well-rounded nutrition. Providing this balanced diet supports their energy and promotes robust health.
