FIG. 2 is a rear elevational view thereof;

FIG. 3 is a left side elevational view thereof, the right side elevational view thereof being a mirror image of the left side;

FIG. 4 is a top plan view thereof oriented such that the rear of the aquarium water heater is at the bottom of the sheet;

FIG. 5 is a bottom plan view thereof oriented such that the rear of the aquarium water heater is at the bottom of the sheet;

FIG. 6 is a right side, front isometric view looking somewhat downwardly on a second embodiment of the aquarium water heater in accordance with my new design, wherein the optional strainer is absent from the bottom portion of the aquarium water heater;
