The Dominant Male Guard the Female and Chases Away Other Males (VIDEO)
Caption
The dominant male spawns synchronized with the female and one subordinate male spawns right after (i.e. out of synchrony and further away from the eggs). The spawning is repeated in slow motion. In this situation there will be an sperm competition where sperm from dominant and subordinate males compete to fertilize the eggs.
