Fish miniatures are small, finely crafted models of fish made from materials such as resin, clay, or plastic, often designed with realistic details and vibrant colors. These tiny decorative pieces are commonly used for aquarium setups, terrariums, home décor, craft projects, and miniature dioramas. They add a lively, aquatic touch to displays and are also popular as collectibles, gifts, or teaching aids to help children learn about different fish species.
