So I have a male and female dovii both about 6 inches. They got along for a few days then the female went ape **** on my male took some fins and left a gash. He is healed up now and I have them separated with light defuser. I figured since the male is not aggressive with the female I just need him to be bigger than her for this to work. So what could I do to get him to out grow her as far as feeding or water changes. And recently my female is showing alot more blue idk if that means anything. And last what is the best temp to keep the tank for dovii?
