The Large Aquarium Isolation Box (Fish Breeder Net) is designed to safely separate delicate, weak, or newly bred fish from more aggressive tankmates—dramatically increasing fry sur vival rates. Made from soft, fish-safe polyester netting and reinforced with a sturdy plastic frame, this breeder box provides a secure environment for newborn fry, injured fish, or territorial species that need temporary isolation. Included suction cups allow you to easily attach the hatchery to the inside top edge of your aquarium, keeping the box stable while maintaining proper water flow and oxygenation. Durable, practical, and easy to install, this isolation net is an essential tool for successful breeding and fish care. Show more
