Keeps fry safe and healthy: Precision filter holes allow steady water flow while preventing fry from being sucked out or eaten by larger fish. This maintains oxygenation and removes light debris without exposing young fish to predators. Improves survival and natural growth: Designed specifically for small fish spawning, the breeder box isolates fry during their most vulnerable stages so they can feed and grow without interruption from adult tankmates. Durable, aquariumsafe construction: Made from sturdy acrylic for clear visibility, longlasting use, and easy cleaning. The rigid material holds shape and resists algae buildup for reliable performance. Versatile multifunction design: Use the unit as a brood chamber for guppy fry or other small livebearers, and as a temporary quarantine area for sick, injured, or newly introduced small fish. The box supports both rearing and isolation needs. Spacesaving, secure installation: Includes strong suction cups and hooks for stable attachment to aquarium walls or corners. Fits compact tanks where floor space is limited and can be positioned at midwater or near the surface depending on your needs. Key attributes Function: fry breeder and quarantine chamber Material: durable acrylic Water flow: precision filter holes for consistent exchange Compatibility: mounts to aquarium walls or corners with suction cups/hooks; suitable for small fish and common livebearer fry Typical uses 1) Rearing guppy or small livebearer fry safely until they reach a size that can tolerate tankmates. 2) Isolating sick or injured small fish for observation and treatment without moving the entire tank population. 3) Introducing , small specimens for acclimation and monitoring before full release into the main aquarium. How it solves common problems Reduces fry losses from predation and overcrowding. Maintains stable water quality around vulnerable fish through controlled flow. Simplifies monitoring, feeding, and treatment while keeping the main tank environment undisturbed. Installation tips Attach the breeder box with the suction cups to a clean, flat section of the aquarium wall or hook it into a corner to minimize movement. Position so filter holes face the main tank flow for water exchange. Clean regularly to prevent clogging of the filter holes and to maintain visibility.
