Aquarium Fish Breeding Isolation Box

Protect newborn fish and breeding pairs with this transparent aquarium breeding isolation box. Designed to provide a safe environment inside your aquarium, it helps separate pregnant fish, fry, injured fish or aggressive species while maintaining continuous water circulation.

Constructed from clear acrylic, the breeder box offers excellent visibility for monitoring fish throughout breeding and hatching. Precision side slots allow fresh water to circulate while preventing small fry from escaping. The floating design and included suction cups provide flexible positioning inside most aquariums.
