Preferred Water Parameters for corydora Weitzman

Corydora Weitzmani, also known as Weitzman’s corydora, is a popular aquarium fish species requiring specific water parameters to thrive.

These South American freshwater fish prefer slightly acidic water with a pH of 6.5 to 7.5. They also require soft to moderately complex water, with a dH range of 2-15.

Corydora Weitzmani is sensitive to poor water quality, so it is vital to maintain good filtration and regular water changes. They prefer a cooler temperature range of 72-78°F (22-26°C), which mimics their natural habitat in the rivers and streams of the United States.

Providing appropriate water parameters is crucial for the health and well-being of Corydora Weitzmani, as they can become stressed and susceptible to disease in unsuitable conditions.

Aquarists can ensure that Corydora Weitzmani thrives in their aquarium environment by monitoring and maintaining the recommended water parameters. 

Weitzman Corydoras Breeding Requirements

Breeding corydoras weitzmani requires some specific conditions to be met to succeed. First and foremost, providing a well-maintained aquarium with clean water and proper filtration is essential.

The water temperature should be kept between 72 and 79°F (22 and 26°C), and the pH level between 6.5 and 7.5. In addition, a diet high in protein, such as live or frozen foods, is essential for breeding Corydoras.

During breeding, it is crucial to simulate the rainy season by performing partial water changes and lowering the water level. This can help trigger the breeding behavior in the fish. It is also essential to provide adequate hiding spots and plants in the aquarium for the fish to lay their eggs.

Once the eggs have been laid, they should be removed from the main tank and placed in a separate tank to prevent them from being eaten by the adult fish. Proper aquarium care and attention to these breeding requirements make it possible to breed Weitzmani Corydoras in captivity successfully.


  • Tank Setup: A separate breeding tank is recommended. It should be at least 10 gallons in size and densely planted with fine-leaved plants like Java moss, spawning mops, or Anubias. These plants provide surfaces for the eggs to adhere to. 
  • Substrate: Smooth gravel or sand is preferred as it will be easier for the fry to sift through for food.
  • Water Parameters: Aim for soft, slightly acidic water with a pH of 6.0-7.0 and a hardness of 5-15 dGH. The temperature should be maintained between 75-78°F (24-26°C).
  • Conditioning: Before breeding, it’s essential to condition the fish with a high-quality diet rich in protein and live foods like brine shrimp or bloodworms.


  • Triggering Spawning: Regular water changes with cooler, slightly softer water can trigger spawning. Mimicking a rainy season in their natural habitat.
  • Spawning Process: The male will chase the female, and they will assume the typical Corydoras “T” position. The female will then carry an egg in her pelvic fins, searching for a suitable spot to lay it. This is usually on the underside of leaves, in spawning mops, or on the aquarium glass. 
  • Egg Care: The eggs are small and sticky, measuring around 2mm in diameter. The parents usually leave the eggs alone, but they can be removed to a separate tank to prevent them from being eaten.
  • Hatching: The eggs will hatch in 3-4 days at a temperature of 75°F (24°C). The tiny fry requires specialized food, such as infusoria or finely crushed flake.

Raising the Fry:

  • Feeding: Once the fry is free-swimming, they can be fed newly hatched brine shrimp, microworms, or liquid fry food.
  • Water Changes: Frequent small water changes are essential to keep the water clean and prevent the fry from developing health problems.
  • Growth: Weitzmani Corydoras fry grows relatively slowly and will take several months to reach adulthood.

Additional Tips:

  • Maintain good water quality throughout the breeding process.
  • Avoid overfeeding the adults, which can lead to poor water quality and hinder breeding.
  • If you are having trouble getting your Weitzmani Corydoras to breed, try lowering the pH of the water or adding some Indian almond leaves to the tank.
  • Be patient! Breeding Corydoras can take time and practice.

You can successfully breed Weitzmani Corydoras in your home aquarium with proper care and attention. These peaceful and enjoyable fish are a great addition to any community tank.
