Based on the name alone, "金鱼西施壶" (Goldfish Xishi teapot) most likely denotes a Xishi‑style Yixing teapot that incorporates a goldfish motif (either as applied sculpture, relief decoration, or a body shaped to suggest a fish). If a photograph shows a different or hybrid execution, that would clarify specifics.

Brief history: The Xishi (西施) teapot is one of the classic Yixing forms developed and popularized in the Jiangsu region from the late Ming into the Qing dynasty. Named after the famed beauty Xishi for its elegant, understated silhouette, the Xishi became a staple of literati and tea connoisseurs for its harmonious proportions and refined simplicity. Over centuries potters have adapted the basic Xishi vocabulary with decorative themes and naturalistic additions—such as fish, plants, or animals—while retaining the form’s traditional virtues.

Shape note: The Xishi profile is typically low and gently rounded with a smooth, slightly flattened belly, short spout, modest lid and a slender, balanced handle—designed for comfortable single‑handed pouring. A goldfish motif adds auspicious symbolism (fish/yu = abundance) and a playful organic accent; when executed in zisha (purple clay), the form also benefits from the clay’s heat retention and tea‑developed patina.
