• Frozen foods (e.g., daphnia, mysis shrimp)
• Dry foods (e.g., sinking pellets, flakes)
• Algae wafers

Feed your Bronze Corys small amounts twice a day. Overfeeding can lead to health problems.

Water Changes

Regular water changes are crucial to maintain good water quality. Perform weekly water changes of 20-25%. Use dechlorinated water and match the pH and temperature of the tank water.

Behavior and Temperament

Bronze Corydoras catfish are peaceful and sociable fish that prefer to live in groups of 6 or more. They are known for their curious and active nature, spending a lot of time scavenging the bottom of the tank in search of food. Bronze Corys are also known for their ability to produce a "chirping" sound when excited or disturbed.

Health and Diseases

Like all fish, Bronze Corydoras catfish are susceptible to certain diseases. Some common health issues include:

• Ich (white spot disease): White, grain-like cysts on the body and fins
• Fin rot: Frayed or disintegrating fins
• Bacterial infections: Open sores or redness on the body
• Parasites: External or internal parasites that can cause a variety of symptoms

Prevention and Treatment

• Maintain good water quality and hygiene to prevent diseases.
• Quarantine new fish before adding them to the main tank.
• Treat diseases promptly and consult with a veterinarian if necessary.

Breeding

Breeding Bronze Corydoras catfish is relatively easy in captivity. Here's a step-by-step approach:

Preparation:

• Condition the pair with a protein-rich diet.
• Raise the water temperature to 78-82°F (26-28°C).

Spawning:
