Amphorae and Vessels

A diving helmet, barrel, cannon or anchor will turn your aquarium into a piece of the seabed. Nobby decorations, roughly 8.5 to 24 cm in size, give fish somewhere to hide, and an amphora or vase can even be connected to an air pump, adding oxygen to the water. Before placing the decoration in the tank, rinse it and check that the openings are large enough that fish can't get stuck in them.
