| Abstract | The fighting fish (Betta splendens) is known for its aggressive behaviour. In the wild, the adult fighting fish areterritorial and show aggressive behaviour. Previous studies showed that adult fighting fish associated withconspecifics showed shoaling behaviour in the laboratory. However, no previous studies have investigated shoalingbehaviour in juvenile fighting fish and it could have implication for commercial breeding. Therefore, we examinedshoaling preference and aggressive behaviour of the juvenile male fighting fish by using binary choice experimentsin the laboratory. When testing these two kinds of behaviour, the test fish were given a choice between a femalejuvenile fish shoal and a male juvenile fish shoal in order to evaluate whether juvenile male fighting fish preferredshoaling with the same sex or different sex before being reared individually. It was found that males showed nosignificant difference either in shoaling preference or aggressive behaviour. However, the size of male test fish waspositively correlated with aggressive behaviour. Therefore, large juvenile male fighting fish should be rearedseparately from shoals in the fish culture. |
