Francis

Francis was a pet fish given to Horace Slughorn by Lily Evans when she was still a student at Hogwarts School of Witchcraft and Wizardry. Lily transfigured Francis into a lily petal, set the petal to float inside a shallow bowl of water, and left the presentation for Slughorn to find. When Slughorn found his gift, the petal sank down in the bowl and turned back into Francis, much to the Professor's delight. Slughorn kept Francis for many years, until the night of October 31, 1981, when he found Francis floating dead in the bowl. He knew this was a sign that Lily was dead.
