A little knowledge makes a calmer tank.
Use these short notes as a starting point while you plan a peaceful community aquarium around a Pygmy Corydoras school.
Think in groups, not individuals.
Pygmy Corydoras are social. Planning the school size first helps determine the tank and companion fish that make sense.
Give them a gentle floor.
Fine sand is the preferred substrate in Bob's care guidance, making it a practical foundation for a Pygmy Cory setup.
Keep the community peaceful.
Small tetras, rasboras, shrimp, and snails are listed as compatible choices. Aggressive fish are not.
Plan the food routine.
Mix quality flakes or pellets with frozen foods and occasional live foods. The current store also carries fine-grain Pygmy Bites.
