Triple-Chamber Fish Breeder Box for Fish Tank, Guppy Fry Nursery | Pregnant fish give birth up top; newborns drop below out of reach of adult fish. Isolates bettas or shrimp in your aquarium.

Features

• Breed, Isolate, Raise - All-in-1 Box: Serves as a hatchery for livebearers like guppies and mollies, an isolation/quarantine cage for sick or aggressive fish (e.g., bettas), a dedicated acclimation space for introducing new fish, and a protected zone where shrimp can molt or feed with confidence.
• Triple-Chamber & Dual-Layer Design: Triple chambers (with dual removable divider panel) let you keep fish or fry apart as needed. The upper compartment lets a pregnant fish give birth, and newborn fry drop into the lower nursery sectionshielding them from adult fish and improving survival outcomes.
• Dual Mounting Methods: The breeder box easily attaches with the included hanging hook or suction cups for flexible placement inside the tank. The adjustable spacer ring sets the box at the right distance from the tank wall so fish wont get trapped. (For stability, keep the breeder box fully submerged during use.)
• Gentle on Delicate Fry: A secure lid with a feeding opening helps keep fish from jumping out. Fine 0.04" slit vents deliver ample water flow through the breeder while keeping even the tiniest fry contained. Crystal-clear walls turn the unit into a fish tank viewing box for observing behavior and health at a glance without disturbance.
• Easy Assembly & Complete Kit: Assembles in minutes with no tools required, and the removable bottom tray makes it simple to clean or release fish. Includes a fine-mesh net for safely catching or transferring fry, and cleaning pipettes for feeding babies or removing waste. Comes with all the accessories you need for convenient fish breeding and isolation.
