Anyone successfully keeping small groups of butterflies?

[skraj011]

Setting up a 6' long 300 gallon fowlr and am considering what fish to add.

I think a small group of butterflies, i.e. 3-4, would be really cool. Has anyone tried this? If you have, which species, how big, what size tank, how did they do, etc?

pyramid butterflies group very well. Hemitaurichthys polylepis

Chaetodon miliaris, C. citrinellus also group v well.

of coz my dream is Chaetodon smithi but that's unobtainable...
