It all depends on how you define "in the end."
But I understand what's being said... I had three Chromis for about three years (46g tank.) They all took turns picking on each other, and they were all about the same size. After three years, one died due to a tumor around its mouth that deformed its mouth. Once there were only two in the tank, there was definitely a pecking order and after about 18 months another one died. So "in the end", I ended up with one - but it took 4-5 years.
