lps/soft coral life span

[fish guru]

How long do these corals live? I have a gsp that is slowy starting to die off while the other corals r doing fine.

Corals on natural reefs can be hundreds of years old. If you tank conditions are adequate and stable they would probably out live you

theoredically, they can live forever. Yes, they do spawn, but some/many reproduce by fragging or fission. Therefore, you really cant put a lifespan on them. GSP will not die of old age.
My best guess would be lack of water flow. They tend to like a lot. but they can also be sensitive to a lot of other thigns such as temp swimg. moreso than a lot of other corals.
