I have to agree with PFitz. Unless you know for certain that you will be able to move up to a larger tank the tangs will eventually go downhill as they outgrow a 55.
CC starfish are not as easy to take care of as their availability would have you believe and no, they aren't reef safe so putting one in would mean you couldn't later upgrade to add polyps or things like that. Starfish in general are very delicate and need a mature, large tank. I think the recommended minimum size for most of the stars is 100 gallons, they won't tolerate acclimation shock, poor water conditions, or many fluctuations at all, and most times their diets aren't really understood all that well so they end up hurting from malnutrition or dying of starvation.
I set up a 55Gal for my cousin a year ago next month, and we put this in there and it is doing great.
1 - Blue Damsel (used to cycle the tank, and then took back to the LFS b/c he was a pain)
1 - White Sleeper Goby
1 - Lawnmower(sailfin) Bleeny (Large)
1 - Yellow Tang (he was about 2 inches whan we put him in and is probably 3 inches now)
2 - Ocellaris Clowns
1 - Coral Beauty Angel
2 - Cleaner Shrimp (Small to medium in size)
50lbs - Fiji Live Rock
Damsels often get aggressive and territorial, that's just damsels. Many also consider it cruel to cycle with them and the whole thing could've been avoided by cycling with a plain old dead raw shrimp instead.
That tang is doing well right now because he's small but you can expect (heck, even HOPE) that he will grow! So eventually he will not be ok in a 55 gallon. At best he will just be in less than satisfactory conditions and live on stressed to some degree (although I sure don't consider that any kind of "best case scenario"!) and he may even become so stressed that he becomes ill and dies down the road.
