Deep Breeding & Isolation Box – 360° Slit Design for Aquariums

Designed with functionality and fish safety in mind, this Deep Breeding Box is perfect for guppy breeding, snail isolation, or controlled feeding setups in community tanks. With its generous depth, it provides ample swimming space while preventing jump-outs—making it ideal for both breeders and hobbyists.

The box features 360° slits for excellent water circulation, ensuring consistent temperature and oxygen levels throughout. Whether you're isolating a fish, breeding snails, or providing a temporary refuge, this box integrates seamlessly into your aquarium setup.

Used successfully in my own tank to breed guppies and raise baby snails for a pea puffer tank—the small snails eventually exit the box, becoming a continuous food source for the puffers.

Key Features:

• Deep enclosure keeps fish safe and secure
• 360-degree slits for maximum water exchange
• Can be used for breeding, isolation, or controlled feeding
• Includes hook attachment and bottom support stand
• Compatible with all rimmed aquariums up to 20 mm thick
• Compact yet spacious design

Assembly Instructions:
After printing, simply superglue the provided hook into the slot on the main box. The bottom support rests against the aquarium glass for added stability.

Whether you're breeding guppies, isolating new additions, or farming snails in a shared tank, this solution keeps things clean, secure, and easy to manage.
