SAFE HOME FOR YOUR FISH: The fish farm isolation box is a great way to prevent attack from adult fish and improve the survival rate of young fish.

It also serves as a refuge for injured fish or to separate aggressive fish from the community DOUBLE LAYER COMBINATION: The Fish Breeding Box features an innovative double-layer insulation design with two separate areas for holding fish and separate bottom compartments that safely collect and protect falling fry. Tiny side and bottom air vents provide optimal water circulation to ensure the healthy growth of newborn fish PRACTICAL AND CONVENIENT: Made of durable acrylic with crystal clear transparency, the hatching incubator allows you to easily and freely observe mother fish and small fish. You can feed the fish through the two holes in the top cover without removing it, to prevent the fish from jumping out of the breeding tank MULTIPLE USES: The aquarium breeding box works great for isolating aggressive fish, injured fish, small fish, shrimp and other marine fish, best suited for carrier livebearing fish such as guppies, flatfish, mollies and swordfish . The versatile incubator box can also be used to display betta (Siamese fighting) fish EASY INSTALLATION: The package comes with strong rubber suction cups for the hatchery isolation box to attach firmly to the side of the aquarium, both convenient and space-saving. With the flexible floating design, you can adjust the position of the insulation box wherever you want
