Have you seen fish with personality?

I had a betta several years ago that used to come up to the surface to take pellets from my fingers. He would watch me come up to his tank and as soon as I picked up the container of food, he would move to the top of his tank. When my fingers would come over the top of the water his little mouth would be up and out of the water waiting for his meal. I had that betta for almost 5 yrs. I really missed him when he died.
