- Enhanced water flow and fry protection: Fine-pore filter holes optimize water flow, prevent fry from escaping, and create a protected ecosystem for healthy rearing in the aquarium. - Reliable juvenile fish protection: A thoughtfully designed guard keeps predators away and enables stress-free growth by controlled separation of fry stages. - Versatile for breeders: Ideal for breeders and aquarium enthusiasts to manage livebearing breeding; enables stress-free separation of aggressive tankmates. - Quick and secure installation: Durable suction cups and hooks provide secure attachment to various surfaces, designed for corner mounting to maximize space in the aquarium. - Practical use scenarios: - Breeding livebearers (eg, guppies, mollies) to protect fry from adults and manage growth stages. - Separating fry from aggressive tankmates to reduce stress and predation during rearing. - Corner mounting in small or space-limited tanks to maximize usable aquarium area.
