Never you'd need a much larger footprint like 8x3. The reasons against a sixty are multitudinous but most importantly stress on the fish either causing it to jump or making it sick and not wanting to eat. If you mean for a day as the only inhabitant maybe but you would need to already own an 8x3 that's cycling.
I could be wrong, I just know a sixty is unsuitable for a monster that will continue to grow. Id recommend a 6'x30" still that is tight corners for a potentially 30"-35" monster.
