I guess that means the rainforests are beyond help... not surprising that we are in the process of destroying the oceans as well, hope we find the medicine before the species that harbors it is extinct.

And yeah, different fish live different amounts of time... I would suspect something like a Neon Goby to have a life span of years, and a lot of larger fish like groupers to have a life span of decades. This is, of course, barring any major incident like a tank crash, power outage, etc. which is likely the major cause (next to improper culture and feeding) of premature fish death.

I have Neon Tetras that are at least 3 years old. Not sure what the lifespan of these is...

I've read that some huge wild Tridacnid clams are estimated to be hundreds of years old (shells of clams have growth rings, like trees). Where I read that, I'm not sure... but I don't doubt it.
