However, a negative correlation was observed between the male age and the number of females that copulated (one day old females: r = -0.621; df=23; P=0.0009) (three days old females: r = -0.786; df=27; P<0.0001).
In the male-male competition experiment, when two differently sized males and one female were combined in one tank on days three and four, the larger male copulated with the female five times, but the smaller male never copulated with the female (Fisher's exact test, 0.05 < P < 0.1).
