🐠The Perfect Aquarium Betta Tank: A 3-gallon nano glass aquarium that's an absolute gem for aquarium enthusiasts! This rectangular beauty is tailor-made for Betta fish, guppies, angelfish, and other small, captivating aquatic companions. Equipped with LED lights, a hanging filter, and lids, we've even thrown in specialized dividers and shields—perfect for hosting two Betta fish, letting them swim with passion and rest in style.
🐙Sleek & Premium Design: The tank measures 12.6 × 6.3 × 8.67 inches (approx. 32 × 16 × 22 cm) — it’s perfectly sized and won’t take up too much space. Made with 4mm thick, high-clarity glass, all four sides feature fully transparent ultra-white glass that offers excellent light transmission and durability, letting you clearly watch your fish swim. A white EVA cushion pad is added to the bottom, blending seamlessly with your minimalist home style. It’s not just a fish-keeping container, but also a small decorative highlight for your home. The custom tank lid serves two purposes: it prevents fish from jumping out and keeps dust out, maintaining a clean tank at all times
