Pay Attention to Water Parameters

Cory Catfish prefer soft, slightly acidic water, with a pH between 6.0 and 7.0, and a temperature range between 72°F and 78°F. Ensure you maintain these conditions by testing the water regularly and performing partial water changes as needed. Keeping the water parameters within the ideal range is crucial for the well-being and breeding of Cory Catfish.

Choosing the Right Tank Mates

Not all fish can coexist harmoniously with Cory Catfish – especially when breeding is in the mix. Opt for peaceful, non-aggressive tank mates like Guppies, Tetras, Cherry Barbs, and Rasboras. Avoid antagonistic species that might eat the eggs, like larger cichlids or predators. Tank mates should not only be friendly but also respect the Cory Catfish’s space and privacy during the breeding process.

The Breeding Process: A Step-by-Step Guide

  1. Check the sex of your Cory Catfish.
  2. Condition the fish with high-quality live or frozen foods.
  3. Perform a water change, lowering the temperature slightly to mimic natural rain.
  4. Look out for breeding behavior, such as T-position or courtship dances.
  5. Monitor your fish closely to ensure safe egg-laying and fertilization.

Securing the Fertilized Eggs

Once the female lays eggs, it’s time to protect them! To enhance the chances of successful hatching, consider moving fertilized eggs to a separate tank or using a breeding box to keep them safe from predators.


  • How can I tell if a Cory Catfish is male or female? Males are generally smaller and slimmer, while females are larger and more rounded – especially when carrying eggs.
  • How long does it take for Cory Catfish eggs to hatch? It generally takes about 3 to 5 days for the eggs to hatch, depending on the water temperature and conditions.
  • What should I feed the Cory Catfish fry? The fry can be fed infusoria, baby brine shrimp, or powdered fry food to provide them with the necessary nutrients for growth.
  • Do I need to change the water during the breeding process? Yes, regular water changes help maintain ideal water parameters and imitate the natural conditions that induce breeding.
  • How many Cory Catfish can I keep in a 20-gallon tank? It’s best to house at least 5-6 Cory Catfish in a 20-gallon tank, as these social creatures thrive in groups.
