Main breeding unit is divided into two upper and lower sections. Either or both upper sections can be removed to allow young fish more room to grow. The unit has an air connection at one end (air pump not supplied) with an airstone which will lift external tank water up through an adjustable spray bar which feeds the top sections of the breeding unit. In this way the water in the breeding unit is constantly circulated and oxygenated. The unit will function as a standard breeding trap if the water circulation system is not used.

Size of unit is : 170mm x 85mm x 110mm.

Suction cups are provided to attach the unit to the inside aquarium glass
