Star constellations are the different patterns that the stars in the sky make up. They do not change their shape.
The actual boundaries of the constellations do not change, but because all stars are moving, the shapes appear to change. e.g. Ursa Major (the Big Dipper) will be a different shape in 100,000 years as the stars that comprise it are all moving relative to each other.

Earth revolves around the sun. That is why the constellations we see from Earth appear to change.
Constellations doesn't take the same shape forever, as over time, the stars that make up the shape start to move away from each other.
Yes, the constellation Eridanus appears to move across the night sky due to Earth's rotation. It generally moves from east to west as the night progresses. This motion can vary slightly depending on the time of year and your location on Earth.
constellations do not have fixed shapes. because they are constantly changing over millennia, and over lap each other. A fixed shape is only how they are or were preceived by the astrologer of the past and present.
