Abstract
Buntbarsch. Das Weibchen laicht die Eier schubweise an einer senkrechten Wand ab, an der sie mit Haftfäden klebenbleiben. Das Männchen besamt in unregelmäßigen Abständen mit schnellen Bewegungen.
Spawning behaviour of a pair kept in isolation. During mating, the sex partners agree on a place for the spawn. They always choose a firm, smooth bed, which can be either sloping or flat. The female spawns the eggs in lots of individual batches, each consisting of about 10 - 15 eggs. The eggs have adhesive filaments and stick firmly to their bed. The male fertilizes the eggs at irregular intervals, more often towards the end of spawning than at the beginning.
