What is the lifespan of the Spotted grouper aka Summan Grouper, Epinephelus summana?
Mine is over 9 years old, and I was just wondering how much longer to expect. He is fully grown and seems to have been slowing down of late, which is making me worried about him. Water is testing perfect, and he is in a 180 gallon with a zebra moray and rock beauty angel. It also has a 100 gallon sump. The tank has been running for about 6 years.
I know some grouper can live many decades, and am having trouble on this species in particular. Thanks. Seems like a lot of detail on the giant grouper and none on this guy :(

not sure how much real data there is on fish lifespans, but I've heard estimates from dozens of years to as much as 80 for many of the larger fish.
most fish die prematurely due to tank conditions or accidents in their care, not actually living their whole lifespan.
there's public aquariums that have said they've had fish for decades and there's koi fish that are reputed to be over 100.
Any answer I gave could give would be made up, but I thought it would be 40-50 years for groupers and other large fish.

It may be that no one really knows?
Certainly large fish like grouper usually have long life spans, but whether that's 10, 20, 30 years, I don't know.

im not finding any good data either. but on the bright side the i did run across a discussion where an LFS employee said that the one they have at the store just sits there doing nothing. so slowing down my not be the evidence of impending doom
hardly scientific i know, but not much else to go by
