Description of life cycle and mating behavior Spawning occurs at night, peaking between 8 pm and midnight. A female spawns almost vertically upward, with her ventral side upstream. She is joined by as many as five males who swim vertically and close to her. As the spawners approach the surface, eggs and milt are released. The fish break the surface, fall over backward, and swim back to the bottom of the pool (Ref. 27547).
