I think she learned to do the fish the way kids learn to draw a star. It's a motion they learn to do, and she wanted to do that simple motion. She's good at knowing a shape she wants to make and drawing it but I think knowing a gesture she wants to make is different.

And then I think when she consciously thinks about it - trying to do it the opposite way, or later the normal way after being judged repeatedly - she can't make the motion that way. But I bet if she was just thinking of the shape and trying to draw that shape it would be zero issue.
