clownfish longevity?

[bencozzy]

i seen a abstract on how making fruit fly females wait to mate made them pass a longevity gene to their young, seeing how some juvie clowns in the wild dont mate for a really long time could they be doing the same thing making their selves live longer lives?

passing a gene to live longer??

anyways the fruit flies the guy has are average twice the normal life span of fruit flys, if im remembering correctly.

just wondering

No clue here, but I have an A. ocellaris that is the third wheel with a pair; the little guy has been with me since '97 and supposedly was purchased in '93. No cleaning of spawning site, no female actions, much smaller then the younger male....who knows how old it is and whether it can make it to maturity under the right conditions.

Scott. Give him a chance. That would make a great experiment. I'm sure he'd be happy to be allowed to mature!

Running out of tank space

fwiw: this little guy has had ample opportunity, I added a quartet of juvenile ocellaris a few years ago and he let the biggest of that bunch become dominant. At the time, it was 2/3 his size.....

My guess is that many can live for quite a long time. I had my female A. ocellaris for 12 years (died last year), and she was purchased as a wild caught adult (in other words, I have no earthly idea how old she really was). I know others have had these fish for longer. Larger species can be expected to live longer, also.

I would think that anything beyond 5 years is well past their expected lifespan in the wild.

Rumors of pairs breeding in captivity for well over 20 years(biggest number I have heard so far is 30 years). We should see if we can find any conclusive and reliable data from the Aquarium in Nice, Steinhart, Shedd, etc.

IMHO: Assuming they are breeding that long in captivity, they likely can live significantly longer then 5 years in the wild as well. Not saying the 20+ as they do in captivity but given the presumed low survival rates of larvae, longer adult lives is a likely the balance.

Just take a look, Terry Siegel had his for about 20 years.

Clownfish can live a lot longer than 5 years. In the wild it is probably shorter on average becuase of preditors and such but they can and do live longer than that. At a LFS where I used to work we had a pair of A. Percula that the owner bought in 91 and they are still kicking and spawning on an almost weekly basis.

I am also interested I had a wild caught ocellans for aground 14 year and one day she just died don't really know how old it was.

WOW I did not know they could live for that long!

 

[dantodd]

I was aware of the repots of 20+ fruitful years in captivity. I was only pointing out that with reef predators and internal pressures of juvenile animals maturing and challenging the breeding pair I doubt that terribly many live nearly that long.

My first clowns were purchased in 86' and i had them untill i sold them in 2000' when we moved. i don't how much longer they lived? when i got them they were no more than 3/4 of an inch long.

I agree with you dantodd, I said in the wild they live shorter lives but in captivity they have no predators so they can live much longer lives.
