    Fluval External Hang On Breeding Box For Fish

    Safely isolate, protect, and acclimate fish without losing precious display space using the Fluval Hang-On Breeding Box. Unlike traditional interior breeding nets that clutter your aquarium and impede water flow, this compact unit mounts conveniently to the exterior of your aquarium frame. Powered by a simple external air pump, it continuously draws fresh, oxygenated, and temperature-regulated water from the main display into the box and back out, creating a stable, gentle-flow haven for fry and delicate fish.
