Description: Automatic system that creates constant circulation both in the maternity ward and in the baby's room. It sucks newborn fries through the tube from the maternity section into the baby's room, keeping them separated, alive and healthy. Once it's set up, there's nothing more to do until the fish is born and deposited in its separate chamber. The Aqua-Nursery also creates constant circulation in both the maternity ward and the baby's room. This eliminates standing water problems found in most other breeding traps and keeps mother and babies alive. Features: Material: plastic. Color: As shown. Dimensions: approximately 20.5 x 9.5 x 12 cm. Contents: 1 nursery aquarium. Note: 1. Due to the light and individual monitor settings, the item's color may be slightly different from the pictures. 2.
