How many days can starfish be kept at home?

If the environment is suitable and properly maintained, starfish can generally live for 3-5 years, and even some species can live for more than ten years.

Starfish, as marine creatures, have special requirements for their living environment. Starfish can generally live for 3-5 years under suitable environment and careful maintenance, and even some species can live for more than ten years. But this does not mean that any starfish can be easily fed at home, and its living conditions need careful management.

In order to ensure the healthy survival of starfish, it is necessary to provide a comprehensive environment including sufficient humidity, light, food and clean water. Starfish have very high requirements on water quality. They need to change water once every half month, but only one third of it is needed to avoid starfish getting sick because they don't adapt to new water.
