Pawfly Aquarium Breeding Box - Transparent Two-Chamber Fry Hatchery for Small Fish

Safe, Smart Breeding Space for Your Aquarium

The Pawfly Aquarium Breeding Box is a compact, transparent haven designed to support fry, shrimp, and small fish in community tanks. Sized at 3.95 inches long, 2.77 inches wide, and 5.1 inches tall, its clear plastic construction lets you observe delicate movements and growth without obstruction. Ideal for 10–40 gallon tanks, it sits securely in the water column, allowing you to keep a close eye on early-life stages while maintaining an orderly, peaceful aquarium experience.

Visual clarity matters when you’re watching tiny swimmers discover their environment. The box’s robust, clear material resists warping and cracking, so you can enjoy uninterrupted monitoring as fry begin to explore their surroundings. The design emphasizes user-friendly maintenance: you can fully disassemble the unit for thorough cleaning between uses, ensuring a hygienic setup for every breeding cycle.

Two Chambers, Two Purposes

Thanks to a removable funnel-like divider, this breeder box creates two distinct rooms. The upper chamber is ideal for isolating aggressive or sick fish, reducing stress and risk for neighboring tank mates. The lower chamber doubles as a practical fry hatchery, giving newborns a calmer space to begin life with easier access to food and oxygenated water.

• Isolate and protect vulnerable fry from larger tank mates
• Provide a dedicated hatchery space that supports early feeding and development

Self-Floating, Secure, and Easy to Use

The self-floating design keeps the breeder box buoyant within the tank, so you won’t have to chase it around as you monitor fry. Two attached suction cups let you secure the unit to the tank wall for added stability. The built-in cover includes two small feeding holes, which helps minimize spills while you nourish young fish and shrimp. Side vents promote consistent water exchange, helping maintain water quality and steady flow through the box.

• Self-floating for stable positioning in the tank
• Secure with two suction cups to prevent movement
• Feeding holes reduce mess while feeding fry
• Side vents ensure smooth water circulation

Practical, Clean, and Transparent

Constructed from sturdy plastic, the Pawfly Breeding Box resists warping and cracking, giving you a long-lasting tool for breeding projects. The clear walls let you observe behavior, feeding cues, and social dynamics without removing the box from the tank. For maintenance, it disassembles completely, making cleaning thorough and straightforward between uses.

• Clear plastic for easy observation
• Disassembles fully for thorough cleaning
• Suitable for a variety of small species, including bettas, guppies, clownfish, and shrimp

With the Pawfly Aquarium Breeding Box, you gain a versatile, low-stress solution to support fry care and early-life stages. It’s designed to fit common community tanks, be easy to set up, and help you keep a calm, well-managed aquarium environment. While outcomes depend on many variables, the box offers practical features that align with common breeding and care scenarios for small fish and shrimp.
