Lippfisch. Paarlaichen: Markierung des Laichterritoriums durch vertikale, loopingartige Schleifenbewegungen eines Prachtmännchens, Laichspurt (0,5 - 1 m aus dem Riff heraus in die Höhe Schwimmen, Abgabe der Geschlechtsprodukte am höchsten Punkt). Gruppenlaichen: gleiche Bewegungen wie oben von einer Gruppe von Fischen, kurzes Auseinanderschwimmen jeweils nach einem Laichakt. Mit Zeitdehnung.

In the protogynous wrasse Thalassoma bifasciatum two different ways of spawning do occur: pair-spawning is performed by gaudy (terminal) males and single females whereas in group-spawning individuals with only the drab color pattern (females and younger mature males) are engaged. In both ways of spawning the movements are similar to each other: In a quick rush the sex partners raise about ½ - 1 m above the bottom towards the open water and release their sex products at the vertex of their upward movement. Thereupon they separate from each other immediately and return to the ground. The behavioral inventory in pair-spawning is enriched by a specific male behavior. The male owns a spawning-territory and marks it optically by more or less vertical looplike jumps. When a mature female approaches the male starts to circle above its sex partner until both are ready for the common spawning rush. Whereas pair-spawning can be seen in all areas that are inhabited by Thalassoma bifasciatum, group-spawning is restricted to well developed reefs with a high population density. The film demonstrates both ways of spawning and their preceding movements in the natural environment at normal speed and with slow motion pictures (64 f/s).
