Abstract
Buntbarsch. Substratbrüter: Zunächst kümmert sich nur das Weibchen um die Brut; es putzt und befächelt die Eier und bringt sie kurz vor dem Schlüpfen in eine Grube unter einen Stein. Nach dem Schlüpfen sind beide Eltern gleichermaßen aktiv bei der Verteidigung der Jungen, die sie bei Beunruhigung mit Kopfrucken warnen.
The film completes the series on the behaviour of the substrate breeder Tilapia mariae. With regard to spawn care, both male and female display dimorphous behaviour. Until the young swim up into the open, the spawn is cared for almost solely by the female; afterwards, both male and female share the responsibility of defending their young. A peculiar yerk of the head is the parents' method of warning the young in case of alarm.
