ABSTRACT:
An improved tank assembly comprising a number of tanks. One of tanks holds the parent fish and has structure for allowing fish larvae to flow into another tank. In the second tank, the fish larvae can circulate and continue to grow. Food is circulated in the tank assembly, and the food particles are collected and prevented from draining out of the tank assembly. The second tank is preferably a circular tank and, once the larvae are in the circular tank, the water current can be adjusted to meet the needs of the fish. This is achieved by an air lift tube carried by the circular tank. The air lift tube operates to exchange water periodically in the circular tank. The air lift tube also pumps live food into the circular tank.
