鱼类的颜色图案通常被用作交流的重要媒介。海葵鱼以特定的白色条纹图案为特征，栖息在海葵宿主中，并将海葵周围的区域作为自己的领地。宿主海葵不仅被海葵鱼使用，也被其他以海葵作为临时庇护所的鱼类使用。小丑鱼也许能够通过颜色图案来识别潜在的竞争对手。我们首先检查了使用 Amphiprion ocellarisa 栖息地的宿主海葵的鱼的颜色模式，并将其与使用周围石珊瑚的鱼的颜色模式进行了比较。尽管在周围的珊瑚中发现了许多带有条纹的鱼，但没有在宿主海葵中庇护的带有条纹的鱼。接下来，向 A 展示了两种鱼模型，一种具有白色条纹，另一种具有黑色背景上的白色条纹。眼集落。对条形模型的攻击行为持续时间明显长于对条纹模型的攻击行为。我们得出的结论是，小丑鱼攻击行为的差异可能选择了共居鱼的颜色模式。这项研究表明，颜色模式不仅可能影响珊瑚礁生态系统中的种内相互作用，而且还可能影响种间相互作用。
Colour patterns in fish are often used as an important medium for communication. Anemonefish, characterized by specific patterns of white bars, inhabit host anemones and defend the area around an anemone as their territory. The host anemone is used not only by the anemonefish, but also by other fish species that use anemones as temporary shelters. Anemonefish may be able to identify potential competitors by their colour patterns. We first examined the colour patterns of fish using host anemones inhabited byAmphiprion ocellarisas shelter and compared them with the patterns of fish using surrounding scleractinian corals. There were no fish with bars sheltering in host anemones, although many fish with bars were found in surrounding corals. Next, two fish models, one with white bars and the other with white stripes on a black background, were presented to anA. ocellariscolony. The duration of aggressive behaviour towards the bar model was significantly longer than that towards the stripe model. We conclude that differences in aggressive behaviour by the anemonefish possibly select the colour patterns of cohabiting fish. This study indicates that colour patterns may influence not only intraspecific interactions but also interspecific interactions in coral reef ecosystems.
