Fish Isolation and Breeding Boxes

Fish Isolation and Breeding Boxes

Fish Isolation and Breeding Boxes are in-tank fish breeding and isolation boxes that give livebearers, small fish and shrimp a separate, safer space inside your aquarium. They suit hobbyists who want to breed fish, protect weaker tank mates or nurture young fish. The boxes float freely or fix to the glass with a suction cup.

Key Benefits

• Breeding haven: gives livebearers such as Guppies and Killifish a safe, comfortable space to spawn, which helps improve the survival rate of the offspring.
• Protection from aggression: keeps smaller or weaker fish apart from attacks by adult fish, supporting their survival and growth.
• Versatile use: works for Bettas, small fish, shrimp, marine fish, livebearers and other aquatic life, so one accessory covers breeding, isolation and rearing young fish.
• Floating or fixed set-up: let the box float freely or attach it securely to the tank wall with the included suction cup.
• Air intake circulation: the Double Box option has an air intake circulation feature that helps keep a steady flow of fresh, oxygenated water moving through the box.

How to Use

• For a floating set-up, place the box in your aquarium and let it float freely.
• For a fixed set-up, use the included suction cup to attach the box to the tank wall.
• Use it to separate a breeding pair or pregnant livebearer, to give a smaller or weaker fish a protected space, or to house young fish away from larger tank mates.
