Here: I'll show you how I started it; “Poor Fish” certainly entails a conflict within oneself, as the main character displays his insecurity in the way of how people view him, especially women. This form of conflict, individual vs. self, is the most important because it comprises the basis of the story, along with its theme. Since the theme of the short story is that love is blind, the main character undergoes a series of change among his conflict within himself. His girlfriend, Ida, happens to help him with this change, and for the better. The author of this short story, Alberto Moravia (1907-1990), pen name for Alberto Pincherle, wrote “Poor Fish” in regard for the Italian visual flair of physical perfection, for beauty was their virtue.  He accounted for a story of the need to want to be physically admirable, and in a successful way when discussing the exploration of the conflict the narrator had with himself. A few reasons the author successfully portrayed the conflict of individual vs. self includes the insecurity the main character has with himself, the uncertainty of Ida’s adoration for him, and the final acceptance of her love for him.  These points in the story actually also represent the conflict, climax, and resolution of the story in exact order. --This is the start of my essay to answer the question, so just go from there and find a few quotes to support your answer (AND PLEASE reword it so we both do not get in trouble for sharing answers) hope this helps.
