Supplementary Information
Video legends
Supplementary video 1. Normal male versus normal female. Pairing of a mature, normal
female with a mature male elicits sexual behavior in the latter. The male displays various steps
(refer to the supporting text) of the mating behavior like following, courtship orientation,
dancing, floating, crossing etc and female remains cooperative and responsive.
Supplementary video 2. Normal female versus normal female. Two females placed together
in the same tank do not exhibit any particular behavior.
Supplementary video 3. Normal female versus AI-treated female. AI-female starts to follow
the normal female, like a normal male. Steps of male-specific sexual behavior like following and
dancing can be seen clearly. However, courtship orientation and other steps are not clearly
displayed by the AI-female probably due to the non-cooperative attitude of the normal female.
Thus, pairing of the AI-female with a normal female never results in mating and gamete release.
Supplementary video 4. Normal male with AI-female. AI-female assumes the dominant
position and starts attacking the normal male. Interestingly, the normal male does not
become subordinate, but it starts to exhibit the male-specific sexual behavior. However, the
treated female continues to attack the normal male and the latter stops sexual behavior.
