Corydoras eques, the horseman's cory catfish or true eques cory,[1][2] is a tropical freshwater fish belonging to the subfamily Corydoradinae of the family Callichthyidae. It was first described by Austrian zoologist Franz Steindachner.[3] It is native to the Brazilian Amazon basin.[4] The name eques means knight in Latin.[5]
The male fertilizes the female's 2–4 eggs between her pelvic fins for around 30 seconds. Only then does the female swim to a suitable location and attach the very adhesive eggs. The couple continues doing this until around 100 eggs have been fertilized and connected.[6]
