siamese fighting fish pale colour, fish duplicate, cylindrical dummy, fish for a variable period without showing aggressive behaviours. The duration of this period depended marginally to the tested cues Fig. 1. Particularly, the cylindrical dummy was inspected just a little longer over other cures, but truly no main alterations were found, aside from the twisting fish reproduction. It may suggest that any international object in the fish territory is worth to be overseen and on the subject of the twisting fish duplicate context, fish felt more threatened thus they preferred to demonstrate competitive shows ahead. This also is supported by the complete duration of the competitive behaviour series Fig.
