Protects newborns: Acts as a separating hatchery for pregnant fish; prevents adult fish from attacking fry and increases survival rates. Secure isolation: Unique clear panel prevents jumping and lets you observe fish without removal; works as a spawning box for viviparous species. Versatile care: Ideal for isolating aggressive or injured fish and for short-term protection of small fish and fry while they recover or grow. Product attributes Function: Separates brood, protects fry, and isolates individual fish for breeding, recovery, or safety. Compatibility: Designed for use with livebearers and small fish species; intended for in-tank placement where isolation or breeding support is needed.
