They would all be in a 46g Bowfront if I do it, which I probably won't. I want to get rid of the 27g Hex that the Angels are in and give them more room to play. The other tank they could go in is a 120g community tank but it already has 4 Angels (2 striped, 2 gold) (same size as the other two), 3 males and 1 female. These two are male/female mated pair (black/white/gold). It is a 48x24x24 120g, if it were the 72" style, I'd be more inclined to do it.
