Isolation Box is designed to protect and manage fish during breeding, recovery, and handling in a safe, clean enclosure. Clear panel isolation and safe containment: Features a unique clear panel that prevents fish from jumping out. Can be used as a spawning box for viviparous fishes. Especially suitable for aggressive fish or injured fish. Spacesaving floating design: Fixes tightly to the inside of the fish tank with three suction cups. Floating, doublelayer construction saves space while keeping the main tank open and accessible. Protective hatchery for newborns: Acts as a separating hatchery for pregnant fish, protecting newborn fry from being attacked and improving the survival rate of the fry. Easy to use and maintain: Detachable box that is easy to disassemble and clean, simplifying routine maintenance and any required setup. 23 practical use scenarios Scenario 1: Breeding livebearing fish in a community tank. Place a pregnant female in the isolation box to provide a calm, protected environment for birthing; after fry are ready, move them to a nursery tank as needed. Scenario 2: Temporary isolation for injured or stressed fish. Use the box to separate and monitor healing without removing the fish from the main tank environment. Scenario 3: Managing aggressive tank mates during breeding. Isolate aggressive individuals or protect vulnerable fry during sensitive periods to reduce harm and improve survival chances.
