The Fluval Hang On Breeding Box 1.9L Large is a spacious, professional-grade external breeding and isolation solution that hangs securely on the outside rim of your aquarium. Designed for serious hobbyists and breeders, this wide 1.9L unit provides significantly more room than traditional in-tank breeder nets — improving comfort, stability, and fry survival rates.
Because it hangs externally, it doesn’t take up valuable swimming space inside your display tank. The built-in air-powered system (air pump sold separately) continuously circulates fresh, filtered water from your main aquarium into the box, keeping parameters stable and oxygen levels high.
