Aquaman: The Legend of Aquaman #1

An Atlantean baby born with the deformity of golden hair, the young Aquaman was left to die on Mercy Reef, but survived due to his ability to breathe air. Surviving as a boy in the ocean on his own, he befriends lighthouse keeper Arthur Curry, who takes him in and gives him the name Arthur. Upon his father's death, young Arthur seeks out and finds Atlantis where he is taken prisoner. He is befriended by Vulko, and upon learning of his mother's death, he escapes from Atlantis and becomes a hero in the surface world. Years later he returns to Atlantis and becomes king.
