New Fish List Suggestions?

[scubasteve]

OK,
I came up with a new list instead of going with my original blue tang, butterfly idea I came up with these:

Fish Already Owned:
1 Bicolor Angel
3 BlueGreen Chromis

New Fish List:
2 Oscellaris Clowns
1 Yellow Tang
1 Fridmani Pseudochromi
2 More Blue/Green Chromis ?? with the hopes that theyll school together with the existing three

How are these picks? I have a 72gallon tank , I think there should be enough room in the tank for them all , if there are two many fish I would probably drop the 2 more green chromis from the list.
Also what order would it be to get these fish in, my QT tank is only 15 gallons so I can't get too many at a time, probably 2 at a time, maybe three if i stay on top of the water changes every day.
Any suggestions, or advice?

I think a 72 is on the small side for any tang, but many will disagree (see below as others post ).
Other than that the list sounds super!!
The chromis should school fine.

I would do them one at a time, with the exception of the clowns, if they are a pair.
Also, if you insist on the tang, place it last...most aggressive fish.
