I've asked this question before and got the answer I didn't weant to hear.....so probably wasting my time again but my lfs has some nice 3" TSN babies for a rediculously low price....I would grow out this fish in my various tanks to around 12" then put it in my 255 which is 84" X 26" x 27"tall is this possible for the life of the fish or will he DEFINTELY outgrow it. I plan to raise the fish on pellets and prawn absolutely no live feeders don't know if that would curtail growth a bit......maybe, hopefully....I have read on some sites that the max size in the aquarium of some of the TSN variants dosen't exceed 2 foot but then I have read some sites claiming 40" is common....guess it depends on the fish to a certain extent obviously......are females smaller than males ?
