Fish vary wildly: 3-4 years for little blennies and gobies. Larger ones, maybe 5 years with the watchmen. Clowns over ten years; some tangs 20 years.
Clams---some, over a hundred years.
Corals---depends on their method of reproduction, but since some reproduce by splitting, in a way there's a chance it dates back millennia.
Anybody got some long-lived ones?
