Description
Product Overview
The HIERYAN Acrylic Breeder Box is engineered for serious aquarists who demand both functionality and durability in a compact footprint. Measuring 6.88 x 3.9 x 5.2 inches and weighing just 13.05 ounces, this lightweight yet sturdy unit fits comfortably into most standard aquarium setups without sacrificing valuable space. Constructed from high‑quality acrylic, the box offers crystal‑clear visibility, superior impact resistance, and long‑term clarity that outperforms traditional glass enclosures. The self‑floating design incorporates a transparent plastic cover that rests gently on the water surface, creating a sealed isolation chamber that prevents fry from escaping while allowing easy observation of their development.
Model number 7400, produced by HIERYAN, reflects the brand’s commitment to precision engineering and marine‑grade materials. The double‑layer combination of acrylic walls and a floating lid ensures that the interior remains protected from external disturbances, such as aggressive adult fish or sudden water currents. This isolation capability dramatically improves fry survival rates, making the box an essential tool for breeding enthusiasts who aim to raise healthy, robust juveniles. The product’s best‑seller rank of #57 in Fish Breeding Tanks underscores its popularity among hobbyists seeking reliable fry protection.
Beyond its core functionality, the breeder box features a replaceable design with double hooks and suction cups, allowing effortless attachment to the aquarium glass and quick removal for cleaning or maintenance. The independent compartment for female fish simplifies the breeding process, enabling users to separate gravid females from the main tank and provide a safe environment for egg laying and hatching. All components are designed for easy disassembly, ensuring that routine upkeep can be performed without stress to the fish or the aquarist.

Usage
Designed for a wide range of freshwater and marine species, the HIERYAN breeder box excels in scenarios where fry vulnerability is a primary concern. Whether you are cultivating guppies, tetras, bettas, or more delicate ornamental species, the isolation chamber offers a controlled micro‑environment that shields newborns from predation and water quality fluctuations. The transparent cover allows continuous visual monitoring, enabling breeders to track egg development, hatching progress, and early fry behavior without disturbing the habitat.
In practice, the box can be positioned in any section of the aquarium that provides optimal temperature and lighting conditions for the specific species being bred. Its self‑floating mechanism automatically adjusts to water level changes, ensuring that the lid remains securely in place even as the tank is refilled or partially emptied. This adaptability makes the breeder box suitable for both permanent fry rearing stations and temporary hatchery setups during peak breeding seasons.
For hobbyists who maintain multiple breeding tanks, the compact size of the HIERYAN box allows for stacking or side‑by‑side placement, maximizing the use of available space while keeping each fry cohort isolated. The double‑layer acrylic construction also helps maintain stable water parameters within the box, reducing the risk of rapid temperature shifts that can stress delicate fry. Users have reported that the box’s design significantly reduces the need for chemical treatments or aggressive filtration adjustments, as the isolated environment naturally limits waste buildup.

FAQ
How do I install the HIERYAN breeder box in my aquarium?
Begin by cleaning the glass surface where the box will be placed. Attach the double suction cups to the acrylic walls, then press the box firmly against the glass until the cups create a secure seal. The self‑floating lid will automatically rest on the water surface, forming a sealed chamber.
Can the breeder box be used for both freshwater and marine species?
Yes. The acrylic material is chemically inert and safe for both freshwater and marine environments. Adjust the water parameters (temperature, salinity, pH) according to the specific needs of the species you are breeding, and the box will function effectively in either setting.
What size fish can be safely housed in this breeder box?
The box is designed for small fry and juvenile fish up to approximately 1‑2 centimeters in length. Larger adult fish should not be placed inside the isolation chamber, as the space is intended for early life stages and may become overcrowded.
How do I clean the breeder box without harming the fry?
When it is time to clean, gently remove the box from the aquarium using the suction cups, then rinse the acrylic components with dechlorinated water. Avoid using abrasive cleaners or harsh chemicals. After cleaning, re‑attach the box and allow the water to settle before re‑introducing the fry.
