Has anyone ever had 2 acro colonies of the same species, but different colors, grow until they were touching/intertwining. I know different colored monti caps can touch and even be grafted together with no stinging or chemical warfare from either color. I'd like to have many colors of A. millepora in my future tank that could grow together into a merged supercolony with no ill effects. Will it be be peaceful or will there be war?
Example of merged monti caps. Not my tank.
