伙伴选择很可能是许多互惠关系中维持合作的重要机制，鱼类之间的清洁互惠关系一直是测试伙伴选择理论预测的模型系统。寻求清洁的鱼（客户）面临两个潜在的问题：清洁工可能会欺骗他们，以纸巾或粘液为食，他们可能不得不等待清洁工的服务。以前的工作之间的相互作用的蓝鳍清洁濑鱼，Labroides dimidiatus，和它的客户端表明，清洁提供更高质量的服务的物种，有选择的切换合作伙伴。这些结果已被解释为证据表明，合作伙伴的选择导致清洁工的行为合作，然而，这些物种间的模式存在其他解释。在这里，我专注于蓝鳍清洁工濑鱼和一个单一的客户端物种之间的相互作用，在其切换合作伙伴的能力不同，以测试预测，客户端接收更高质量的服务时，清洁工必须竞争获得他们。结果表明，当华丽蝴蝶鱼（Chaetodon ornatissimus）的客户可以更换合作伙伴时，清洁工会优先获得他们的服务;然而，当华丽蝴蝶鱼可以访问多个清洁站时，它们被欺骗的频率并没有减少，而且它们经常通过积极追赶清洁工来应对欺骗行为。结合以前的工作，这些结果表明，合作伙伴的选择影响蓝鳍清洁濑鱼和他们的客户之间的合作互动，但一些客户端的能力，切换合作伙伴可能会使用其他策略（即惩罚），以限制清洁作弊。(C)2010年，动物行为研究协会。由爱思唯尔有限公司出版。保留所有权利。
Partner choice is likely to be an important mechanism for the maintenance of cooperation in many mutualisms, and cleaner mutualisms among fish have been a model system for testing predictions of partner choice theories. Fish seeking to be cleaned ( clients) face two potential problems: cleaners may cheat them by feeding on tissue or mucous, and they may have to wait for service from a cleaner. Previous work on interactions between the bluestreak cleaner wrasse, Labroides dimidiatus, and its clients indicates that cleaners provide higher-quality service to species that have the option of switching partners. These results have been interpreted as evidence that partner choice leads cleaners to behave cooperatively; however, alternative explanations exist for these between-species patterns. Here I focus on interactions between the bluestreak cleaner wrasse and a single client species that varies in its ability to switch partners to test the prediction that clients receive higher-quality service when cleaners have to compete for access to them. The results indicate that cleaners give ornate butterflyfish, Chaetodon ornatissimus, priority of access to their services when these clients can switch partners; however, ornate butterflyfish are not cheated less often when they have access to multiple cleaner stations, and they frequently respond to cheating by aggressively chasing cleaners. In combination with previous work, these results indicate that partner choice influences cooperative interactions between bluestreak cleaner wrasse and their clients, but that some clients with the ability to switch partners may use other strategies (i.e. punishment) to limit cheating by cleaners.
