Growth environment: The tuned pore size traps dirt particles, regulates water flow, and minimizes stress for young aquarium inhabitants. Improved survival: A specialized protection system shields fry from adult tankmates and enables undisturbed development for natural rearing. Versatile fish care: High-function acrylic breeding box for guppy fry and small fish; optimizes rearing and enables effective quarantine in the aquarium. Keeps juveniles safely separated while maintaining water circulation. Easy installation: Stable suction cups and hooks provide secure attachment to a range of surfaces; designed for corner mounting to maximize available space in the aquarium. Use scenarios: - In a community tank with adult fish, protect fry during early life to improve survival rates. - As a quarantine module for new fry before introducing them to the main tank. - In compact or nano aquariums, corner-mounted to keep the center area open and available for swimming.
