The Nido 3.1 XL is an extra large breeding box made of net material. Young fish and pregnant fish have plenty of room to grow and give birth here. Due to the special size of the breeding tank, the young fish grow quickly. An ideal supply of fresh, clean and oxygen-rich water is always guaranteed. The Nido 3.1 XL has a double bottom so that the young fish have the opportunity to find a safe place immediately after birth. Thanks to the removable partition in the middle of the Nido 3.1 XL, two pregnant fish can be separated until successful delivery. Sick, aggressive or suppressed animals can also be easily separated in the Nido 3.1 XL.
