Years ago when they were bred all the ones that we're not marked right were just disposed of. At least know there not being killed. I never liked clowns but these platinum are nice and for $50 for both I couldn't pass it up. Becoming my favorite tank mates.
I got a pair of designer clowns a while back and I like them. They still have the normal stripes but the head and middle stripe are connected on top. Here's a pic. They were expensive but worth it in my mind, not lighting maroon expensive though $150 for the pair.
