Breeding boxes are a handy product designed to aid in the protection of eggs and newborn fish fry. They ensure any offspring produced are safely separated from the other aquarium inhabitants, including their parents. This in turn will increase their survival rate. You can even place the pregnant female in the box prior to egg deposition, or giving birth, in the case of livebearers. Using the grill provided when the female deposits her offspring they will fall through to the floor of the box and be protected from the mother by the grate. 

Breeding boxes can also be used to isolate diseased, weakened, bullied or aggressive fish. The Superfish Breeding box is a floating model that is placed into the tank itself. Suitable for both freshwater and marine aquariums.
