Individual differences in behavior are observed in the variety of ways animals respond to environmental challenges, interact in a social group, take risks to access a resource, and so forth. In the present study, we investigated the behavioral reactions of male and female Siamese fighting fish () in different contexts and how they affect female mate choice. A total of 100 females and 50 males were classified according to boldness, sociability, and aggression, and then female mate choice was observed based on male profile and body color. Our results showed sex-related differences in Siamese fighting fish behavioral profiles: Males exhibited a higher correlation with aggression and females with boldness. Both male and female behavioral profile affected female mate choice. Females preferred bold red and nonaggressive red males. Sex-related differences in behavioral profiles may reflect ecological differences between male and female Siamese fighting fish. Female mate choice could be related to behavioral profiles that indicate better parental care, as male features may influence parental care decisions and the development of offspring behavioral profiles.

个体行为差异表现在动物对环境挑战的各种反应方式、在社会群体中的互动方式、为获取资源而冒险的方式等方面。在本研究中，我们调查了雄性和雌性暹罗斗鱼（）在不同环境下的行为反应，以及这些反应如何影响雌性的配偶选择。总共对 100 只雌性和 50 只雄性进行了大胆、社交和攻击性分类，然后根据雄性特征和体色观察雌性的配偶选择。我们的结果表明，暹罗斗鱼的行为特征存在性别差异：雄性与攻击性的相关性更高，而雌性与大胆性的相关性更高。雄性和雌性的行为特征都影响了雌性的配偶选择。雌性更喜欢大胆的红色和不具攻击性的红色雄性。行为特征的性别差异可能反映了雄性和雌性暹罗斗鱼之间的生态差异。雌性的配偶选择可能与表明更好的亲代照顾的行为特征有关，因为雄性特征可能会影响亲代照顾决策和后代行为特征的发展。（PsycInfo 数据库记录（c）2021 APA，保留所有权利）。
