I do have three clowns, I was gonna get 1 and wife wanted a "nemo and marlin" as I did some research I found that 2 was a bad number for clowns so I got 1 extra. What I read was clowns are all born male and who ever is the largest in the school will become female. If you have just two they will fight till one dies ? So the number was 1 or 3 or more. Is this True ?
