According to your description, I understand this. I wonder if it's right: the bedroom door is in the north. After entering the room, there is a fish tank in the west wall and a bed in the east. If the bed is in the east-west direction, it doesn't matter if the fish tank is here. If the bed is placed in the north-south direction, that is, one side of the bed faces the fish tank, it needs to be adjusted, but it doesn't matter.
In fact, don't care too much about these, as long as the room is reasonably tidy. Because architecture is not too important for feng shui, if feng shui is followed, then no building can live in people.
