External Fish Breeder Box for Fish Tank with USB Pump Aquarium

• 【3-IN-1 BREEDING & ISOLATION, ALGAE REFUGIUM & BIO-MEDIA CHAMBER】Designed as a versatile aquarium breeding box, isolation box and baby fish nursery, it provides dedicated space for pregnant livebearers, newborn fish, newly introduced fish and injured fish requiring temporary separation. When not used for breeding, isolation or baby fish care, the multi-purpose chambers can hold macroalgae as an algae refugium or bio-media for supplemental aquarium filtration. A practical alternative to a traditional breeding net, mesh breeder or fish tank divider.
• 【ADJUSTABLE WATER FLOW, USB PUMP & VIBRATION-DAMPENING DESIGN】The included 2W 92 GPH (350 L/H) submersible pump provides continuous water circulation between the main aquarium and breeder box, while the inline flow-control valve lets you adjust the water flow. Dual shock-absorbing foam pads help reduce vibration transfer to the aquarium glass for quieter operation. Powered by a low-voltage 5V USB connection with a 1.5m cable; compatible with standard 5V USB power sources or power banks. USB cable included; wall adapter is NOT included.
• 【SPACE-SAVING EXTERNAL HANG-ON DESIGN & WIDE TANK COMPATIBILITY】This external hang-on breeder box mounts outside the aquarium to preserve valuable swimming space inside the fish tank while keeping fish easy to observe. Designed for rimless aquariums and compatible framed tanks, it fits aquarium rim or glass thickness up to 0.63" (1.6 cm) and requires at least 5.9" (15 cm) of horizontal mounting clearance.
• 【W-SHAPED BABY FISH SEPARATOR & MULTI-CHAMBER NURSERY】Two upper isolation compartments provide separate spaces for pregnant guppies, mollies, bettas, newly introduced fish or injured fish. The W-shaped separator features 0.8–1mm micro-slots that allow newborn fish to move into the lower baby fish nursery while helping separate them from larger fish. Dual access openings make feeding and daily care more convenient without removing the entire lid, while the covered design helps keep fish inside.
• 【DUAL FILTRATION & 20-PCS AQUARIUM CARE KIT】Dual inlet and outlet filter foams help capture debris while helping protect baby fish around the water inlet and outlet. The multi-purpose chamber can hold bio-media or macroalgae for supplemental aquarium filtration or refugium use. Made from durable, high-clarity PC for easy viewing. Includes 10 washable filter foams, 3 plastic droppers, algae cleaning sponge, waste pipette, fish net, cleaning brush, tweezers, water outlet lid and extra water pump extension tube.
