First, you probably already know this..but a reminder. You dont want more than one angel in a tank. Sometimes you can get a dwarfs to coexsist, but its not the norm.
Butterfly's are considered "advanced" usually because they can be very delicate.
Tangs in a 55 are frowned upon. Even one in a 55 isnt good. They are sprinters and need 75-100gallons (when full grown) to be happy.
If it were me, I would put the clowns, one angel, and maybe a few anthias. If you havent looked at them, I would suggest it. Very colorful, perfect for the smaller tank, and relatively inexpensive. They are also very active and will school. However, I would caution that you research what kind your tank and skills can handle. A barlets anthias is very easily kept, but a purple queen requires live food several times a day.
