Pygmy Corydora Care Guide with Aquarium Size Requirement:

1. Species Overview:

  • The Pygmy Corydora (Corydoras pygmaeus) is a small and peaceful freshwater catfish species native to South America. Known for their charming appearance and social behavior, they are a popular choice for community aquariums.

2. Aquarium Size:

  • Provide a tank with a minimum size of 10 gallons for a small group of Pygmy Corydoras. Larger tanks of 20 gallons or more are recommended for larger groups.
  • Keep them in groups of at least six individuals as they are social and feel more secure in numbers.

3. Water Parameters:

  • Maintain a stable water temperature between 72°F to 78°F (22°C to 26°C).
  • Aim for a slightly acidic to neutral pH level, ideally between 6.0 and 7.0.
  • Keep the water hardness in the soft to moderate range, around 2 to 15 dGH.

4. Size of the Fish:

  • Pygmy Corydoras typically grow to a size of about 1 inch (2.5 centimeters).

5. Tank Decor:

  • Set up the aquarium with fine gravel or sand substrate to mimic their natural habitat. Provide hiding spots with caves, driftwood, and live plants.
  • Ensure open swimming areas, and use gentle filtration to avoid strong currents.

6. Diet:

  • Pygmy Corydoras are omnivores. Feed them a balanced diet of high-quality sinking pellets, flakes, and occasional live or frozen foods such as bloodworms and brine shrimp.
  • Offer small and frequent meals to accommodate their small size and energetic nature.

7. Behavior:

  • These corydoras are peaceful and enjoy the company of their own kind. They exhibit schooling behavior, and a group of Pygmy Corydoras is a delightful sight in the aquarium.
  • They are bottom-dwellers and will sift through the substrate in search of food.

8. Tank Mates:

  • Choose tank mates that are small, peaceful, and compatible with the water parameters suitable for Pygmy Corydoras.
  • Suitable companions include small tetras, rasboras, and other non-aggressive community fish.

9. Tank Maintenance:

  • Perform regular water changes of 20% every two weeks to maintain good water quality.
  • Use a filtration system suitable for the tank size to provide proper water circulation.

10. Breeding:

  • Pygmy Corydoras can be bred in captivity. Provide a separate breeding tank with fine-leaved plants for egg deposition.
  • The water in the breeding tank should be slightly cooler, and small, frequent water changes may trigger breeding behavior.

By following these care guidelines and providing an appropriately sized and well-maintained aquarium, Pygmy Corydoras can thrive, adding charm and activity to a community aquarium.
