And/or what’s the longest confirmed time you know of one living for? I know many places say they have a lifespan of 10-15 years but I have yet to hear about anyone having one for that long. I know many fish tend to die prematurely for a variety of reasons and most fish don’t live as long as they could in captivity. I assume public aquariums are going to have some of the oldest ones. Does anyone how long that is?
