He used to be such a sweet fish! Never got mad, never attacked anything. But now when I come near him, he takes one look at me and his head puffs up, he gets a little bigger, and then he runs and hides behind the plastic plant. Sure, one time ACCIDENTALLY, I was pouring water in after cleaning his tank and the water hit him and made him do a flip. I apologized profusely, though. Does he just hate me?
