Perfect for Breeding & Fry Protection

This multi-purpose fish incubator is specifically designed to serve as a spawning and breeding chamber for viviparous fish such as guppies, mollies, and platies. By creating a secure and well-oxygenated environment, it greatly increases the survival rate of baby fish (fry), giving them a fighting chance without the threat of being eaten or injured by other tank mates.

Connect the isolation box to an external oxygen pump to increase oxygen concentration and promote healthy development. Whether you’re raising delicate juveniles or preparing for new fish arrivals, this incubator is a must-have addition to any home aquarium setup.

📏

Spacious & High-Quality Acrylic Build

Unlike other small breeder boxes, our isolation tank is made with high-quality cell-cast crystal acrylic, offering exceptional clarity and durability. With generous external dimensions of 6.69” x 6.1” x 3.14” (17 x 15.5 x 8 cm), it provides ample space for fry or injured fish to swim comfortably.

The included Betta hammock adds additional enrichment and comfort for resting or nesting fish, standing at approximately 3.15 inches (8 cm) in height. The polished edges and seamless finish ensure safety for delicate fins and scales.

🔒

Dual-Layer Isolation for Safety & Convenience

Designed to isolate aggressive, injured, or small fish, this aquarium breeder box features a smart double-layered system. The upper and lower compartments allow you to separate different fish without needing multiple tanks. A transparent cover prevents fish from jumping out, while two feeding holes in the top make it easy to provide food without removing the lid.

Whether you’re preventing injury from bullying or giving your fry a quiet space to grow, this box makes fish care stress-free and efficient.

Floating & Flexible with Suction Mounting

This breeder box offers a self-floating design, allowing it to be easily repositioned anywhere within your aquarium. Included high-quality suction cups provide extra stability and make it effortless to mount on any smooth tank wall. Move it, float it, or fix it in place — you’re in full control of your setup.

Enhanced Internal Water Flow Design

Fish health depends on consistent water quality — and this box is built with that in mind. Featuring fine crevices on both sides, it ensures continuous water flow between the isolation box and the rest of the tank. These 1mm gaps prevent baby fish from escaping while allowing clean, oxygen-rich water to circulate naturally, maintaining a healthy and stable micro-environment.
