great excuse for a new tank!Stocking suggestions?

;DHey guys, i've been away for a while but i'm back with a new purpose.

About 2 months ago my wife and i found out we are pregnant with our first child. As i'm sure you can understand it's pretty exciting news.
We have already set aside one of our spare bedrooms as the new babies room.
Figuring we will be spending lots of time in there with nightly feedings and just watching the baby sleep i figured, "why not start another tank in the babies room"!
I saw an ad for a 75 gallon at my LFS and i'm going to buy it. It's salt water ready. Guy wants $75.00!

Anyway, my plan is to have a FOWLR. The only fish i am going to put in there from my reef is the damn Powder Blue Tang that is messing with my Elegance!
Obviously "NEMO" will have to be in there, but the rest are up i the air. This is the reason for this thread.

I want to stay away from any other Tangs,no wrasses either.

I was thinking some Angels and/or Butterfly's

The thing is i know nothing about these fish since i only have a Coral Beauty in my reef and thats it.

I'm open to other suggestions but really would like some suggestions on some different types that will be compatable.
What Butterflys are easy to keep as i hear they don't fare well in captivity.
How many will be reasonable for stocking a tank that size?

Thanks in advance for any help.

 

I have a lovely potters angel now and he is a fantastic little fish. Some say they can be pretty timid though and with your powder blue that could be an issue.

 

A copperband would be a great addition, as far as angels go though, i would stick to dwarf angels. A flame would be great.
