30 gal centerpiece fish ideas

Thanks for all the suggestions. :)

I think I might get a GBR, if I can find a nice one at my LFS. I already have another tank I can transfer it to, if it ends up being too aggressive.

If I do need to move the GBR out of my community tank, I'll probably try a dwarf gourami next.
 
Neon dwarf rainbows (bright turquoise with red fins) or some of the other rainbows. As their name suggests, you can get them in most colors :-)

A mixed school of Congo tetras and boesmanii rainbows (blue and yellow) is really cool.

A pair of marbled angels

A pair of pearl gouramis (as someone else also suggested.)

A Bolivian ram would be nice and get some size...but would stay nearer the bottom.
