与石珊瑚共生的虫黄藻利用居民鱼类种群排出的氨。然而，还没有研究过海葵鱼产生的铵对宿主海葵的贡献。在分裂对实验室实验与巨大的海葵Entacmaea quadricolor，一个一半的每只海葵保持与两个人的地方性海葵鱼Amphiprion bicinctus，和另一半保持没有海葵鱼。海葵碎片保持与海葵鱼再生显着快于那些没有海葵鱼。再生8周后，有海葵鱼的海葵触手中的内共生藻类（虫黄藻）比没有鱼的海葵触手中的内共生藻类（虫黄藻）更多。成年海葵鱼（8厘米的总长度）每个排泄铵的速率约为0.97亩M小时（-1）。海葵已保持4个星期，没有海葵鱼，以更快的速度比那些一直保持与海葵鱼，其中吸收很少的氨从丰富的水吸收氨。我们的结论是，海葵鱼提供氨为他们的主机海葵和zooxanthropium，提高组织生长和再生率。
Zooxanthellae symbiotic with stony corals utilise ammonium excreted by resident fish populations. However, the contribution of ammonium produced by anemonefishes to host sea anemones has not been examined. In split-pair laboratory experiments with the giant sea anemone Entacmaea quadricolor, one half of each sea anemone was maintained with two individuals of the endemic anemonefish Amphiprion bicinctus, and the other half was maintained without anemonefish. Sea anemone fragments maintained with anemonefish regenerated significantly faster than those without anemonefish. After 8 weeks of regeneration, there were more endosymbiotic algae ( zooxanthellae) in the tentacles of sea anemones with anemonefish than in those lacking fish. Adult anemonefish ( 8 cm total length) each excreted ammonium at a rate of about 0.97 mu M h(-1). Sea anemones that had been maintained without anemonefish for 4 weeks took up ammonia from enriched water at a faster rate than those that had been maintained with anemonefish, which absorbed very little ammonium. We conclude that anemonefishes provide ammonia for their host anemones and zooxanthellae, enhancing rates of tissue growth and regeneration.
