Common name: Starfish

Asterias is a genus of starfish in the family Asteriidae. Members of this genus are commonly found in the shallow waters of the Northern Atlantic and are known for their distinctive five-armed shape. They play a crucial role in marine ecosystems as both predators and prey. In the aquarium, they can be fascinating additions but require a well-established tank with plenty of live rock for grazing and hiding. They are sensitive to water quality and should only be introduced to mature, stable environments.
