They can get to around 3 foot in captivity. Now they are a fairly flexible fish obviously, and at those large sizes are not OVERLY active (but still pretty active), so you're not going to need a 5 or 6 foot wide tank, but you should be looking at a 4 foot wide tank for a fish that can reach 3 foot.
Something like a 10 by 4.
When I was a kid I had a 2 foot micro, and by that time it had started to look cramped in a 180, so my dad gave it to someone with a bigger tank.
