- Large brood box: measures 17.5 x 16 x 8.5 cm and is designed to enclose fry, significantly reducing predation and improving survival. - Easy observation: made of acrylic, with suction cups to attach to the tank wall for a clear view and uninterrupted interaction with the fish. Installation and removal are tool-free. - Multi-room design: a two-layer configuration isolates aggressive fish. Includes a bottom incubator and two removable dividers to create three separate chambers, without taking extra space. - Wide application: floating transparent cover protects fry from adult fish and keeps them inside the isolation chamber, increasing their survival rate. Typical uses: - Protect newborn fry in a community tank from larger tank mates while they grow. - Create three separate zones in a tank by using the removable dividers, safeguarding fry in a controlled area. - Observe breeding and feeding behavior easily with the clear acrylic construction and simple attachment.
