Butter koi fry? How big is your tank? Is the dovii male or female?

You need a bigger tank.

You need a bigger tank.

+1. The Dovii will need something bigger just for itself. That could be a major reason why you are having aggression issues. Nuttall has a similar stock as yours and he is having the same problem. I wouldn't suggest adding anything else until you get a much larger tank.
