is the water level of a 40-high fish tank? Generally, the water level of a 40-high fish tank is about 35 centimeters, or less. Usually, the reason for not filling the tank with water is to prevent the fish from jumping out of the tank, leaving a certain amount of space so that the fish will not jump out. It should be noted that the water level should not be too shallow, once the water is too little, it will make the water quality difficult to maintain, but also reduce dissolved oxygen, which is also very harmful to the breathing of fish.
