Is it me or how could a Jag fit in a 40 gallon for five years!!! First off, those fish are not healthy especially that poor Jag-Jags are supposed to get anywhere from 12-16 inches-I would suspect if you posted a pic of your friends Jag that it would look deformed. There is no defending this guy!! And no he didn't make it work-yes the fish are alive but it does not neccessarily mean they are happy and healthy. I could live in my room for the rest of my life and eat hot dogs only-I may live for awhile-that doesnt neccessarily mean that I am happy or healthy.
