I got to thinking, and would two pairs in two side by side tanks help strengthin the bonds between the pairs? My reason for thinking this is that the males will probably spend most of their time fighting the other male in the tank right on side of it, lessoning the time spent hassling the female. Is this genious... or just plain stupid? Also, what species forms stronger bonds, Labiatus, Citrinellum, PetSmart mutt?
