Order

Common name: Sea Anemones

Scientific name: Actiniaria

Actiniaria, commonly known as sea anemones, are a diverse order of marine, predatory animals named for the anemone, a terrestrial flower. They form a key part of reef ecosystems, often engaging in mutualistic relationships with clownfish, which gain protection from predators by living among the anemone's stinging tentacles. Sea anemones are valued in the hobby for their vibrant colors and dynamic presence. They require stable water conditions and benefit from targeted feeding of meaty foods. Some species can reproduce asexually in the aquarium, leading to a proliferation of individuals if conditions are favorable.
