How to Breed Panda Corydoras: A Peaceful Guide to Raising Tiny Bottom Dwellers
Panda Corydoras (Corydoras panda) are one of the most endearing freshwater fish available. With their playful behavior and panda-like markings, they’re a favorite in community and species tanks alike. Thankfully, breeding them isn’t too difficult with the right setup and a bit of patience.
Choosing and Conditioning a Breeding Group
Start with a small group of at least six to ensure a healthy mix of males and females. Males are typically smaller and slimmer, while females are rounder and more robust when carrying eggs. Allowing a group to form naturally increases the chances of a compatible spawning trio or pair.
To prepare for breeding, feed the group a rich diet of live or frozen foods such as bloodworms, daphnia, and blackworms. A well-fed group is more likely to spawn, and the females will become visibly round with eggs.
Triggering Spawning Behavior
In the wild, Panda Corydoras spawn during the rainy season. You can mimic this in the aquarium with a large, cool water change—drop the temperature by a few degrees using soft, slightly acidic water. This often stimulates the fish to begin courtship behavior.
Males will begin to chase the females and initiate the classic “T-position” behavior, where the female takes sperm into her mouth to fertilize eggs she holds between her pelvic fins.
Spawning and Egg Care
Females will deposit sticky eggs on smooth surfaces like glass, plants, or decorations. Spawning can result in 20 to over 100 eggs, depending on the female’s condition and age.
To prevent predation, you can either remove the adult fish after spawning or gently move the eggs to a separate hatching container. Adding an air stone and a small dose of methylene blue can reduce fungal growth. Keep the water well-oxygenated and clean, and the eggs should hatch in about 3 to 5 days.
Raising the Fry
Newly hatched fry are tiny and will feed on infusoria or commercial liquid fry food for the first few days. After that, transition to powdered fry food and then to live baby brine shrimp or microworms as they grow.
Keep up with frequent small water changes to maintain pristine conditions. Sponge filters are ideal, as they provide both gentle filtration and a safe surface for young fry to graze on biofilm.
Final Thoughts
Breeding Panda Corydoras is a calm, low-stress experience compared to many other freshwater species. As long as you provide clean water, a stable environment, and a nutritious diet, these delightful little fish will often do the rest themselves. Watching them grow from tiny fry into playful, active adults is one of the most satisfying experiences in the hobby.
