Help with adding 2nd clown

[Trommell]

Hello Everyone,

I added two Black Storm Clown fish when I started my tank in July of last year however after about a week in the tank one of the two clownfish died without any outward sign of aggression/disease/parasites and all other fish were unaffected. Fast forward and long story short, I would like to add a second clownfish back to the tank but I am uncertain on a few things. The clown fish is 2-3in long have I waited long enough for the clownfish to change to a female, when I do add another clownfish is there a size ratio to stay within to ensure the male doesn't get murdered? Should the clown regardless of size stay in acclimation box for extended time to keep from too much aggression, and anything else that I am not thinking about that I should be before? Any help would be greatly appreciated.
