The Nido 3.1 XL is a particularly large pure breeder. It offers young fish and mothers-to-be plenty of room for growth and birth. Thanks to the large size of the pure breeder, young fish grow quickly. An ideal supply of constantly fresh, clean and oxygen-rich water is always guaranteed. The Nido 3.1 XL is also equipped with a double floor that allows the newborn young to escape from safety immediately after birth. The removable compartment in the middle of the Nido 3.1 XL allows you to keep up to two mothers-to-be separate from each other until they give birth. Also, nervous, aggressive or frightened animals can be ideally separated in the Nido 3.1 XL
