the tang police tend to flame for anything viewed as unnecessarily fast, not required, not enough, too much, etc...but im not flaming them, as they are right sometimes.
with that being said, i ALMOST bought the same puffer a few days ago, but i decided not to, because of the brackish thing as they get older. i have heard of them staying in fw their whole life, but they get better color, and more personality out of sw.
