This is just my opinion but in as much as I have a yellow Sailfin and a Kole in my 110 I can give you my observation. The yellow is the alpha, my Kole will compete for food with him but when push comes to shove Kole gives way to the yellow they are both relatively the same size. I am more and more thinking Bang is correct that the ability to swim feely is a major factor in keeping them but in my case the kole is an open swimmer
