Corydoras Breeding Triggers — Spawning Induction & Fry Rearing

Corydoras breeding is among the more accessible tropical fish breeding experiences, featuring the distinctive T-position mating and rain-simulation spawning triggers.

Easy-to-Breed Species

Corydoras paleatus (Bronze Cory), C. aeneus (Green Cory), C. panda, C. sterbai.

Spawning Trigger Technique

1. Two weeks of intensive feeding with frozen bloodworms and brine shrimp
2. 50-70% water change
3. New water 2-3C cooler than tank water (simulating rain)
4. Low barometric pressure days tend to trigger spawning

T-Position Mating

The female positions her mouth against the male's abdomen in a T-shape, collecting sperm. She then holds eggs in her ventral fins and attaches them to glass surfaces or leaves.

Egg Management

Collect eggs to prevent parental consumption. Add dilute methylene blue for fungus prevention. Hatching occurs in 3-5 days depending on temperature. Remove white, opaque infertile eggs promptly.

Fry Rearing

Newly hatched fry absorb yolk sac for 2-3 days. Feed brine shrimp nauplii 3-4 times daily. Introduce powdered food after 2 weeks.
