You can certainly do this by giving them each their own space by using a wire fine mesh to keep them split or placing them in plastic material containers with holes in it to let circulation of water.
Which method you chose, ensure that the adult males cannot see one another.
When Siamese fighting fish ready to fight, the adult males will flare off at one another, almost doubling or tripling in proportions to intimidate his opponent. Their gills and fins definitely will flare out and their colors could become more extreme.
