I'm selling 2 of the males in my tank next weekend. There is a total of 6 fish in my 30g. 3 males, 2 females, and 1 juvi around 1" long. My question is should I separate my dominate male from the other fish? I don't want the others to be harassed more due to being 2 less fish in there.

I have a tank full of fry and plan on putting some more females in there eventually or I can get a couple more adult females from where I got these from. What do y'all suggest?
