The XINYOU XY-380 Sponge Filter is a popular, highly efficient, and low-maintenance air-driven internal filter designed for small to medium-sized aquariums. It provides excellent dual mechanical and biological filtration by pulling water through a high-density, bio-friendly foam sponge using an external air pump setup.\r\n\r\nBecause it creates a gentle current and physically protects inhabitants from getting trapped, it is widely considered a staple for shrimp tanks, breeding setups, fry holding tanks, and delicate species like Betta fish and Discus.
