They said it was moved from being too "aggressive" . Our area is small so i dont know what type of home he is going to find... Not all of us have a huge pond or 500gallon tank.FriarThomasIII said:

This is absolutely possible. The sponge filter isn't really acting as a filter, it's mixing oxygen into the tank water. The tank keeper is obviously removing and replacing most of the tank water every few days to maintain good water conditions for the fish. So, a filter isn't really needed. If you change out a lot of tank water every few days, you don't need a filter at all, just some gizmo like an air stone attached to an air pump to move the surface of the water to mix oxygen into the water. This action is called "gas exchange". Oxygen mixes with water to release carbon dioxide.
