Ziss BL-3T EZ Breeder Box
The Ziss BL-3T EZ Breeder Box is a premium in-tank breeding and grow-out box designed to provide young fish and shrimp with a safe, highly oxygenated environment while keeping them within the stable water conditions of the main aquarium.
The BL-3T features fine stainless-steel mesh across the base and sides, allowing excellent water exchange while keeping fry safely contained. An additional plastic bottom beneath the mesh provides extra protection and ensures water remains in the box even if the aquarium water level temporarily drops.
An external airlift continuously draws fresh aquarium water through the breeder box, helping maintain excellent oxygenation and consistent temperature and water parameters. The flow can also be adjusted to suit delicate fry or stronger-swimming juveniles.
With a capacity of approximately 2.4 litres and dimensions of around 14 × 14 × 15 cm, the BL-3T offers plenty of usable space without taking over the aquarium.

Why We Like It
The BL-3T is particularly useful when raising young fish that benefit from plenty of fresh, oxygen-rich water while still needing to be protected from larger tank mates.
Unlike basic breeder traps, the mesh and airlift system provide constant water exchange, making it a much better option for serious breeding and grow-out work.
