Product description
Product description 3D Printed Aquarium Breeder Box – Air-Driven Fry Tray (UK-Made) Give your fry the best possible start with the Finatics Aquatics Air-Driven Fry Tray — a spacious, air-powered breeder system designed to safely raise fry while maintaining excellent water quality and oxygen levels. Proudly designed and 3D printed in England, this tray combines functionality, durability, and flexibility for hobbyists and breeders alike. Using a gentle air-lift circulation system, water is continuously refreshed from the main aquarium, helping maintain stable conditions without exposing delicate fry to strong currents or hungry tankmates. Suitable for freshwater, brackish, and marine aquariums. Key Features ✅ Gentle air-driven circulation keeps fry oxygenated and safe ✅ Continuous water exchange helps maintain stable water quality ✅ Large capacity and roomy design for improved fry growth ✅ Adjustable mounting system fits a wide range of aquariums ✅ Expandable design using optional connecting rods ✅ Strong, easy-to-clean 3D-printed construction ✅ Designed and manufactured in the UK Perfect For Raising livebearer fry and baby fish Separating injured or weak fish Acclimating new arrivals safely Temporary observation or isolation setups Why The Tray Is Not Fully Transparent Unlike many breeder boxes, our fry trays are intentionally not fully see-through. While a clear box may look better to us, it is often far more stressful for the fry inside. Constantly seeing larger fish outside the tray trying to eat them can cause unnecessary stress and panic in delicate fry, especially during their most vulnerable early stages. The more enclosed design helps fry feel safer and calmer, encouraging healthier behaviour, feeding, and growth. The priority of this design is the survival, comfort, and development of your fish — not just visibility.

Directions • Attach the fry tray securely to the aquarium using the adjustable handles • Screw the air lift component firmly into position before use • Connect the clear uplift tube and ensure it is fully secured • Attach the filter component securely to the clear tube before operation • Ensure all filters and components are properly fitted before adding fry • The filter system helps prevent fry from returning to the main aquarium • Connect airline tubing from an air pump to the air driven circulation system • The tray will naturally find its operating water level depending on airflow and filter resistance • Clean the filter regularly as desired to help maintain lower water levels and consistent flow • Fill the tray to the recommended operating water level • Place fry or small fish into the tray gently using a net or container • Monitor water conditions regularly to ensure optimal fish health • Clean periodically using aquarium safe cleaning methods • Rinse before first use • Avoid using very hot water during cleaning

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.
The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
