No one really knows how long anemones live. You can ask in the anemones & clownfish section on this forum. They will most likely tell you the same thing.
The life expectancy is much longer than any of us will have tanks. We don't know exactly what it is, but anemones can live for a very long time. They may even be theoretically immortal. You can be certain that your anemone is not succumbing to old age.
Most often shrinking is a result of poor nutrition.
had mine 22 years still as pretty as ever and yes its one of the few things that can live for ever i have a condy they say they move around tank he does not been in sae place for years the clown fish play in him he dont mind them at all i do supplement feed once a week i take krill chop it up real fine put in turkey baster let him wrap wrap around it and release it slowley your may be lacking food
I finally replaced my MH light yesterday . I never realized that is over 8 months. It seems that it's perking up again. Thank you all for the post. My clown is happy again .

Unless you're keeping deep sea anemones, this almost certainly isn't the case even though it may be possible in theory.
In the wild, the average BTA only appears to last around 10 years. A few individuals live a few decades. We know that they can actually live about 3 times that long at least though.
Some other anemones like Condylactis don't even last as long as BTAs in practice.
they can live forever they split or whatever and keep on thriving tell my 22 year old she was only suppose to live 10 years she sits on her rock she is the star of the tank never ate a fish shes well fed
They "could" live forever in theory, but they don't. Most of ours in the lab are over 20 yrs old as well. That doesn't change the fact that in the wild, they only last about 10 years on average.
Sorry, I worded that incorrectly. The article said in theory they could. As in, if they constantly had food, light, and perfect conditions without predators or diseases to interfere, they could. It certainly never said it was likely though.
