hi mate mine are in a 3ft x 18 x 18 at the moment , i have 6 in there and well planted with no problems at all , it could well be that you have two males and a female , personally i would add another 3 to the tank , if that is not an option do as gigas says and give a bit of time to settle and then if not try removing the bully . you could allways post up a pic of your set up there in so we can have a look and see if there is anything else we can see to make them settle more
