generally a bad plan, I wanted both so a LFS i trust hand picked 2 of the same general size and I added them at the same time, they didnt care about each other one bit, till ich got my flame. I have been reading about the 2 ange thing all over the internet and most sya dont do it. I have found a few posts ( ill try to dig them up and post links) that claim you can add a second angel if the new one is slightly larger, my same LFS says the same but reccomends against it being a Flame, different dwarfs would be better.
