The Fluval Hang On Breeding Box 1.1L Medium is a compact yet spacious external breeding and isolation solution designed to give fish extra room while keeping your main display tank untouched.
Unlike traditional in-tank breeder nets, this unit hangs securely on the exterior glass rim of your aquarium, preserving valuable swimming space inside your aquascape. Its built-in air-powered system (air pump sold separately) continuously draws water from your main tank into the box, ensuring stable parameters, steady oxygen levels, and healthier fry development.
The 1.1L size is perfect for hobbyists who want a professional-style breeding or acclimation setup without the bulk of a larger unit.
