they will not grow that big because your small tank will stunt their growth and shorten their lifespans

Thanks for your help, but that didn't tell me anything I didn't state above.
6-12inches in a tank, not 3 FEET. That's what I expect, and it's not too big for my 55gal.
That's 4 fish 12-14 inches each TOPS. I highly doubt they'll even get that big in the next 5 years.
But if for some reason they got 3 FEET, I would make the appropriate changes.
