why won’t my siamese fighting fish eatThe diameter of circles represents the frequency of the behaviour, total distance travelled or time spent close to stimuli normalized between 0 and 1. FD – frequency of frontal display; LD – frequency of lateral show; Ch – frequency of charge; CS – frequency of caudal swing; Ap – frequency of method; AB – frequency of air respiration; TD – total distance travelled; TC – time spent near stimuli. Lines within groups constitute Pearson’s correlation coefficients r, with line thicknesses proportional to r value and useful / poor correlations indicated by line colour green / yellow, respectively. 001Although women have not been without delay selected for combating, alterations in competitive behaviour among traces were akin to those followed for males. 10; Fig. 2, see Additional file 1: Figure S1 for individual aggression measures.
