Pygmy Cory (Corydoras pygmaeus)

The Pygmy Cory is one of the smallest and most adorable catfish in the aquarium hobby. Unlike most corydoras, these tiny fish don’t just stay on the bottom—they often swim together in the middle of the tank, making them incredibly fun to watch.

They’re peaceful, active, and perfect for planted aquariums and nano community tanks. When kept in groups, Pygmy Corys are confident, social, and constantly exploring every corner of the aquarium.

Why people love Pygmy Corys:
• One of the smallest cory catfish available
• Peaceful and perfect for community tanks
• School together in the middle and bottom of the aquarium
• Great for planted and nano aquariums
• Safe with shrimp and other peaceful fish
• Full of personality despite their tiny size

Pygmy Corys do best in groups of at least 6, but the larger the group, the more natural and active they’ll be. They enjoy planted aquariums with sand or smooth gravel, gentle water flow, and plenty of hiding places. They’re excellent tank mates for tetras, rasboras, shrimp, and other small, peaceful fish.

Feed a quality sinking micro pellet along with crushed flakes and occasional frozen foods like baby brine shrimp, bloodworms, and daphnia. While they’ll help clean up leftover food, they should still be fed a balanced diet to stay healthy.
