Description of life cycle and mating behavior During the spawning process, corys assume the so-called "T" position, with the male assuming the top part of the "T" and the femalae oriented perpendicular to him (Ref. 44091). The male stirs up the female with his barbels on her head and back; the female collects sperm in its mouth; lays down about 20 eggs (yellow in color, 1 mm in size) which she collects with her pelvic fins, then fertilizes them and fixes them to submerged rocks or plants. Such sequence takes place for 2-3 hours, thus resulting in spawning of 100-200 eggs. Several spawnings are possible in the same season. At 22°C, hatching occurs after 5 days, the vitellin being absorbed 3 days later (Ref. 35381).
