When urine was introduced the likelihood of courtship or mating (6 out of 15 pairs showed mating attempts) was similar to mating or courtship success generally found when staging intersexual encounters for a limited time in a small aquarium (7 out of 15 in control experiments; in other experiments 7 matings were recorded in 17 pairings; Fiona C. Berry, unpublished results).
We then measured the time until the male touched a hermaphrodite and showed mating behavior (first contact) and until the first time the spicule was inserted (spicule insertion).
