Oooo..a black n white angel tank. Very cool! I've seen one before; I'll have to hunt down the post when I get back from work.
In the meantime, figure around 10g per angel to determine tank size. You might want to look at 5 in a 55g; this way theres some room for fish to run to when 2 decide breeding is in order (boy can they be aggressive buggers!). Taller tanks are better then longer for angels
btw, they need the room for their fins. Keep the water current to a minimum; they hate fast water (they aren't built for it).
Buncha choices for the fish morphs. One of the black morphs, a marble, an albino blushing, a silver and a half black would look awesome, although some of those may be hard to find. Check out the different phenotypes here:

My mated pair is a prime example. He's a huge male almost 4 inches in body length and another good 5 in tail length, she's a tiny lil slut...erm..female
LOL about 2 1/2 body length and 2 fin length. They look like the high school football player and his cheerleading g/f
LOL
I like the idea of the yoyos; I've 3 in my 55g with the angels (along with 3 clowns and a plec) and they are extremely amusing *grin* They don't mess with the angels, although they will follow them around from time to time looking fascinated
LOL. I agree skunks wouldn't fit in color wise; they are also very aggressive.
