Before the actual spawning
we notice the following:
1. The female stays permanently in a “probing” position.
2. The respiratory frequency and intensity of both female
an dominant male increases some minutes before oviposition.
3. Prior to spawning the females removes vigorously her
anal fin into the gravel.
4. The female starts the spawning gap some fractions of
a second before the male.
5. The frequency and intensity of attacks between adults
have increased significantly some minutes before oviposition.
