This study tested whether mated pairs of Texas cichlid (Cichlasoma cyanoquttatum ) would reform and continue rearing their offspring after being separated for either one, four, or ten days. All pairs successfully re-formed after one day, while only 50% re-formed after 4 days. No pair re-formed after 10 days of separation. In successfully re-formed pairs, the female was always more aggressive than her mate, irrespective of whether the female was the resident or the returning individual. Aggressiveness seemed related to the female's attempt to control the male's parental behavior. For pairs which did not re-form, the resident parent, either the male or female, violently and continously attacked the returned mate.
本研究测试了德州丽鱼(Cichlasoma cyanoquttatum)的配对亲鱼在分开1天、4天或10天后是否会重新组合并继续抚养它们的后代。所有亲鱼在分开1天后都成功重新组合,而在分开4天后只有50%重新组合。分开10天后没有亲鱼重新组合。在成功重新组合的亲鱼中,无论雌鱼是留居者还是返回者,雌鱼总是比配偶更具攻击性。攻击性似乎与雌鱼试图控制雄鱼的亲代行为有关。对于没有重新组合的亲鱼,留居的亲鱼,无论是雄鱼还是雌鱼,都会猛烈且持续地攻击返回的配偶。
