Goldfish (2017)

More than anything in the world, Stratis, a sensitive 7-year-old boy, wants a pet for his birthday. And much to his dad's chagrin, he is determined to have one. As the father and son embark on a mission to find the perfect animal, with dad insisting on buying a more 'masculine' pet, Stratis spots the ideal companion: Tom, an unusual, silken little goldfish.
