Fish and aging

I was just on a website that was telling about fish and one of the things they said was the life expectancy in captivity. Most of the fish besides a few different types were only 2-4 years. Is that anyway to tell how old fish are or if you have an old fish? Thanks!

I would say size really, if you research the fish and know its growth rate you should be able to get it within a good frame. 2-4 years isn't correct from what ive witnessed on others.
My dad has had a Tang for 6 and has had at least 3 others that are 5. He told me when I started mine, good water flow to keep them strong, meaty supplements to keep them strong, and they will last if the water stays good. Hes been in the game for at least 8 years and his tank is amazing. My true idol. His dad was an ol schooler though. No skimmers and no filters. WC and lots of them and LR. I remember him saying. "Why do you need a machine, the ocean dosen't need a machine!" he had great reef tanks also. Ill see if I can pull up some of his old polaroids and scan them.
Anyways im rambling.

nope and according to scott micheals book alot of fish lifespans are longer in captivity than they are in the wild. pretty much all you can tell with most fish are juvenile state or mature (some fish develop colors, shapes, humps and things). Captive clownfish usually arent that old when sold and tangs and clowns live so long it really doesn't matter (20+ years. some reports speculate tangs can live 30+ years). with clownfish you cant even go by size since a male can stay small forever and since they all start as males....For wild caught fish I'd just go by size (excluding clowns and probably others I dont know of). You have to figure being in the ocean there cant be much there to stunt growth like there might be in captivity. If a wild fish is small consider it young. If its huge consider it at least not young.

Do some research before you call me out.He probably had red bellies(skittish) not blacks.They each have thier own tank.They must live alone,or they would fight till the death!

Xcali1985, thank you for sharing the info from you father, I think that is some of the best advice I have seen. I guess good flow would be the same as us exercising and staying healthy, I just never thought of it that way. Thank you.
