A combination filter and motorized pump for mounting on the wall of an aquarium. A housing containing a removable filter tank and electric heater is connected by an upper casing to a screw-type of water elevator adapted for positioning within the aquarium, the said housing being positionable outside of the aquarium wall. The top of said casing comprises a platform supporting an electric motor, the said screw elevator extending up through the floor of the casing and being connected by shafting to said motor. A deflector disc is mounted on said shafting for deflecting water downwardly to protect the motor and direct the water to the casing floor from which it flows downwardly through the filtering and heating compartments of the housing, and then upwardly through lateral passageways to correspondingly positioned spillways, the latter being integral with hook members supporting the device on the rim of the aquarium.
