I don't want many fish, but the two that I really hope can live in a tank this size are a powder blue tang and a copper band butterfly. 
 
what does everyone think about those fish in a tank that size? I know people normally say 6 foot minimum for a tang like that, but I have zero experience with cubes, so I'm not sure if that gives you more options in terms of fish. 
 
Any thoughts?

 Tangs are swimmers. They swim to and fro and need the length that larger tanks provide.
Anyone who has had a 3 or 4 footer can attest that the longer tank is more suitable for tangs.  I think you know that.
Like almost all reefers I have not been able to keep a CB lontg enough to determine their spacial needs.
