海葵鱼（Amphiprion; Pomacentridae）和宿主海葵之间的互利关系是众所周知的，但宿主海葵也被雀鲷（Pomacentridae），濑鱼（Labridae）和红雀鱼（Apogonidae）用作庇护所。三点Dascyllus trimaculatus（Pomacentridae）是已知的生活或附近的主机海葵在其未成熟的阶段。然而，有关其他鱼类利用海葵作为宿主的详细研究尚未进行。为了了解影响其他鱼类利用海葵的因素，本研究调查了琉球群岛海葵周围的鱼类生物群。除两栖类外和D.此外，还发现了10种鱼类（9种雀鲷和1种红雀）暂时利用海葵作为庇护所，以及5种濑鱼（包括弯唇鲷）来清洁海葵。Logistic回归分析（自变量：是否存在其他鱼类;因变量：海葵鱼的攻击性，宿主海葵的大小，D。trimaculatus）表明，宿主海葵的大小对鱼类的存在很重要，无论是在使用海葵作为临时避难所的物种还是在清洁物种中。大型宿主海葵可以为其他种类的珊瑚礁鱼类以及海葵鱼提供庇护所和食物资源。
The mutualistic relationships between anemonefish (Amphiprion; Pomacentridae) and host sea anemones are well known, but host anemones are also used as shelter by damselfish (Pomacentridae), wrasses (Labridae) and cardinalfish (Apogonidae). The threespot dascyllusDascyllus trimaculatus(Pomacentridae) is known to live on or near host anemones in their immature phase. Nonetheless, detailed studies on the use of host anemones by other fish species have not yet been conducted. To understand the factors that influence the use of host anemones by other fish species, this study investigated the fish biota around host anemones in the Ryukyu Archipelago. Other thanAmphiprionspp. andD. trimaculatus, 10 additional species of fish (9 species of damselfish and 1 species of cardinalfish) were confirmed to temporarily use host anemones as shelter, and five species of wrasse includingLabroides dimidiatuscame to clean anemonefish. Logistic regression analyses (independent variable: presence or absence of other species of fish; dependent variables: anemonefish aggressiveness, size of host anemone, number ofD. trimaculatus) indicated that the size of host anemones is important for the presence of fish, both in species using the anemone as temporary shelter and in cleaner species. Large host anemones can provide shelter and food resources for other species of coral reef fish as well as for anemonefish.
