What would you do?

So I currently have 3 randalls anthias ready to come out of quarantine this weekend. 1 male and 2 female. Well this morning I found the male and the bigger female ( who is noticeably more aggressive with the small female) locking jaws and going at it. After work I found the small female and male being chased all over (by the up and coming male). Now I know I can't add all three to my dt, so which would you add? The very laid back male or the feisty female that is on the verge of turning male? Any help deciding will be appreciated!
