Another fact for you regardin clowns is that the bigger of the 2 will be the female and if they were both male to start with the more dominant one (ie the bigger of the 2) will change sex to become the female, how wierd is that, theres people that pay to have that done and these things just do it naturally.
Also the black one is not refered to as a maroon clown as maroon clowns tend to be solitary unless introduced very young also true maroon clowns will not tolerate any other type of clown and become aggresive, so the black one is another percular clown just different colour.
