Just for the record, that tank at big al's is NOT 2000gal. It is 1346gal. I went in and measured it personally one time. Tank is 10x6x3tall.
A fish 3ft long really should be in a way bigger tank than even 4 or 500 gallons.

First of all the obvious, the bigger the tank, the better. AT LEAST three times the length and twice the width of the maximum size of the species you have in mind...

This quote was taken from an article on
wetwebmedia.com and written by
Bob Fenner and is well supported with references. This is probably the mimimum reccomendation I have ever seen for swimming space too. I remember in one 'coral' magazine (or maybe tropical fish hobbyiest?) they suggest 5x the length x 3x the width. The fish just will not do well without the swimming room, or live to their full potential.
