IMO Picasso clowns have a jigsaw puzzle random patern to the bars. Snowflakes have a body that is almost a solid blotch of white. Some people will say that Picasso clowns are true percs, and snowflake are ocellaris, but I have seen some TRUE PERCS with almost solid white blotch bodies, that I would call snowflake, but maybe somebody has a better name for them. Both are example of Overbar clowns which seems to be an inherited trait-unlike misbar-which is less white and usually assocaited with poor larval conditions.
