ichthyologist:Sperm Drinking Corydoras CatfishSeveral species of Corydoras catfish are known for their unique method of mating, which involves the female drinking the male’s sperm.When these fish reproduce, the male will present his abdomen to the female. The female will then latch her mouth onto the male’s genital opening, creating the well known ‘T-position’ many species exhibit during courtship.The female drinks the sperm released by the male. This sperm rapidly moves through her digestive tract and exits within a couple of minutes. It is discharged simultaneously with her eggs into a pouch formed by her pelvic fins, fertilising them in the process.During this period, the female can swim away to deposit her eggs in private. In the wild, the eggs are laid on aquatic plants whereas in the aquarium, they are often deposited on the glass.(C. sterbai depicted)Image: Jan Ševčík; Gif from duandr1 via Youtube -- source link
