Rock Flower Anemone Lifespan?

[mistyw]

Hi all! I have had three rock flower anemones in my tank for about two years. I now have four babies as well. My question is, does anyone know the general lifespan?

They are essentially eternal from a total lifespan standpoint, disease/changes in their environment can shorten and end their life however.
If given the correct conditions over a lifetime, they would outlive us without any problem.
