tempting fate? adding another dwarf angel.

[spikehs]

i currently have 2 angels in my 50gal (coral beauty, and a false lemon peel) I've pretty much come to the conclusion that I wont be able to have any sort of sps (although they have left my one frag alone... for now). How do you think I could maximize my chance for success in adding a flames angel? I figure if I get a really small one that'd be the best chance, and leave the lights off for a bit..
