Most study's say they don't live much past 30. How old did you want it to be?
That's irrelevant - I am simply stating that I think that blues will live as long as there surroundings allow them to. 30 year old catfish don't die of old age! Animals and people are always surpassing life expectancy - IMO a 138 lb blue is older than 23....
So your just ignoring scientific data because in your opinion the fish is older?
How old do you think I am, maybe I could get social security.
But seriously, man has no natural predator but ourselves and we die of old age some at 50 some at 100 some older some younger, you cant expect them to live forever. Alot of aquarium fish have a life expectancy of 2 years... not much.
