I'm so glad you decided not to divide the tank. Bettas are a gorgeous and personable fish and deserve a very minimum of 5 ...
One of my more interesting tanks over the years has been a betta sorority tank. So many beautiful colors and they all got along great! They may not have the long flowing finnage you like to look at, but the females would come right up to the glass if I approached the tank and would come to my fingers when I would clean the tank. Silly little girls.
Did you ever have caves for them? One member suggested a cave for the betta so he can go in it for shelter and security. I like that idea, especially if it will make my fish more comfortable, but having a hard time finding one small enough for a 5 gallon with a big enough opening. I found this that I am considering.
