- Essential must have for fish breeding: separates pregnant fish from fry, protects newborns from attacks, and improves survival rates of the young. - Easy maintenance: detachable box design that is simple to dismantle and clean, with no tools required. - Versatile isolation box: features a clear panel to prevent fish from jumping out; can also be used as a spawning box for viviparous (livebearing) fish; especially suitable for aggressive or injured fish. - Safe and observable: provides a secure enclosure for small fry while you monitor them with ease. Use scenarios: - During pregnancy: place the expectant mother in the box to protect the fry as they develop. - Post birth or for viviparous fish: use as a spawning/holding box to shield newborns and control the environment, while keeping them visible. - Isolation and recovery: move aggressive or injured fish into the box for safe quarantine without disrupting the main tank.
