It is an ovoviviparous species, not really territorial which shows nip﷓right order. In this research, significant differences of spatial distribution have been found according to the position in the nip﷓right order and according to the sex of the fish. These differences bind with two external variables: the presence of sexual partners and the space available for the fish. The dominating males prefer a space partition allowing access to the females more than a compartment allowing access to more space in volume. They also chase their subordinates in the contiguous compartment of the aquarium. Females swordtails prefer the bigger compartment independently of the presence of conspecific males. These results are discussed in the light of reproductive strategies particular to each sex. date: 1986 date_type: published publication: Naturaliste Canadien (Rev. Écol.
