Background on the side.

If the fishtank is near the door, does it make sense putting the background foil from the right side of the tank where the door is, to not stress the fish?

Yes, definitely. Sudden traffic through the door would be extremely stressful to many fish. Another thing to be aware of with doorways is temperature changes.

Thank you. The door leads to a bedroom and the fish are subtropical. Temp change should be ok i hope
