Abstract
Buntbarsch. Das Weibchen legt die Eier ab, dabei stößelt das Männchen die Ventralseite der Partnerin. Wenn das Weibchen die Eier mit dem Mund aufnimmt, dreht sich das Männchen und schleift seine Genitalpapille über den Grubenboden, das Weibchen saugt daran und nimmt so Spermien auf.
The film covers the behaviour of an isolated Tilapia variabilis pair during spawning. With this species, the female takes the eggs into her mouth immediately, before they have been inseminated by the male. She then sucks at the male's special genital tassel and in this way takes in sperms.
