Excuse me, as shown in the picture, can the fish tank be placed next to the kitchen door in feng shui?

Reasonable. Fish tanks and memorial tablets are not suitable here. I don't know if you have heard of the fortune in Feng Shui. In other words, the creatures responsible for swimming in Feng Shui, such as fish tanks and turtles, are not placed in front of the kitchen. But where to put it depends on the location of your home, your local geographical environment and divination. Pay attention to the right time and place.
