This isn't really for fish long-term (it's too small), but it makes a beautiful decorative piece. It's a clear glass bowl, about 15cm wide and 10cm high, sitting on a rustic wooden ring base. You can use it as a tiny vase for a few flowers or floating candles, as a terrarium for air plants or succulents, or even as a holder for colorful stones or seashells. Some people do put a single betta fish in it, but please research proper betta care as they need heated, filtered water. It's more of a stylish accent piece for a desk, shelf, or coffee table that brings a bit of natural, minimalist beauty to your space.
