An interesting (though maybe not entirely on-topic) tidbit...
http://www.cnn.com/2003/TECH/science/11/19/offbeat.old.fish.ap/index.htmlOn Tuesday, aquarium officials at the Steinhart Aquarium honored an Australian lungfish, aptly named Methuselah after the Old Testament's millennia-old character.
Methuselah arrived at the aquarium in 1938 as a fully grown adult.
That makes it at least 65 years old and the oldest fish in captivity, aquarium officials said after having researched collections at the world's other aquariums.But now I'm curious as to how long this kind of fish would normally live... and, for that matter, what other records there are for fish lifespans. Fish usually breed quickly and die fast; ones that live very long have to be relatively rare, I'd think...
