Description of life cycle and mating behavior | In Tahiti, spawning starts near full moon with the formation of schools of several thousand fish at various depths. The fish remain almost motionless for between 1 to 3 hrs, then change their normal color to pale grey. About 4 or 5 fishes rise a few yards above main school and swim around each other discharging milt and eggs, then return to former place and replaced by another group to spawn. |
