Tanks essentially act as ponds but are generally constructed of concrete or fiberglass. Wood can also be used but must first be treated to prevent rotting. Concrete tanks have the advantage of being less expensive, easily constructed and formed into various shapes.

 Plastic, fiberglass or glass tanks are ordinary tanks which are either designed and constructed for rearing fish or used for storing water. They can be moved from one place to another.

 Wooden troughs are constructed with planks. They vary in size and depth. After construction, the tank is lined with nylon to prevent leakage. It can be moved from one place to other.
