Breeding & Spawning Loxozonus Cory: Reproduction protocol

Loxozonus Corydoras are relatively easy to breed in an aquarium setting. Here is a general protocol for breeding and spawning Loxozonus Corydoras:


  • Set up a breeding tank: The breeding tank should be at least 10 gallons in size and have a fine-grained substrate, such as sand or gravel. The water should be soft and slightly acidic, with a pH between 6.0 and 7.0. The temperature should be between 72-78°F (22-25°C). 
  • Condition the breeding group: A few weeks before breeding, select a breeding group of 4-6 fish, with a ratio of 2 males to 1 female. Feed them a high-quality diet rich in protein, such as live or frozen brine shrimp, bloodworms, and daphnia. This will help them grow healthy and promote egg production.
  • Simulate the rainy season: To trigger spawning, simulate the rainy season in their natural habitat by performing large water changes (approximately 50%) with cooler water (a few degrees cooler than the regular tank temperature). You can also increase the water flow and aeration to mimic the movement of water during a storm.


  • Courtship: When the female is ready to spawn, she will become noticeably rounder with eggs. The males will start to chase her around the tank, displaying their pelvic fins and nudging her with their snouts.
  • T-position: The male will then position himself in front of the female and grasp her pectoral fins with his mouth. This is called the “T-position.”
  • Egg laying: The female will release a single egg, which the male will fertilize. She will then pick up the egg in her mouth and carry it to a suitable location, such as a plant leaf, piece of driftwood, or the glass of the aquarium. 

After Spawning:

  • Remove the parents: Once the spawning is complete, remove the adult fish from the breeding tank. This will help to prevent them from eating the eggs.
  • Maintain water quality: Keep the water in the breeding tank clean and well-oxygenated. Perform small water changes (10-15%) every few days to remove any waste products and prevent fungal growth.
  • Hatching: The eggs will hatch in 3-5 days, depending on the water temperature. The fry will be tiny and will need to be fed infusoria or other small live foods for the first few weeks of their lives. 


  • To increase the chances of successful breeding, you can add spawning mops or other fine-leaved plants to the breeding tank. These will provide a safe place for the female to lay her eggs.
  • If the adults are not spawning after a few days, consider lowering the water temperature by a few degrees. This can trigger spawning.
  • Be patient! It may take several attempts before you are successful in breeding Loxozonus Corydoras.

The female holds eggs between her pelvic fins, where the male fertilizes them, and swims to a spot where she attaches her eggs. Only after the female swims to a suitable spot does the female attach the very sticky eggs, ensuring eggs have been fertilized. The pair repeats this process until about 100 eggs are securely attached.
