How many meters can our champion archer shoot?

The shooting technique of water-shooting fish is quite clever, and the "water bomb" shot within one meter can hit every shot. It has been found that there is a groove-like structure in the upper part of the mouth of the water-shooting fish, which is bonded with the tongue to form a tube. If the tongue moves up and down naturally, a series of "water bombs" will be ejected from the mouth. So why do archerfish have such superb shooting skills? Biologists used a high-speed camera to shoot the segmented action of the water-shooting fish to launch the "water bomb", and then they found out the secret of the "sharpshooter" in the water. It turns out that sunlight will refract when it enters the water from the air, and the refraction of light will produce errors. Interestingly, when aiming at the target, the water-shooting fish will make its body vertical to the water surface, and at the same time, its eyes are very close to the water surface, so that the "water bomb" emitted can overcome the deviation caused by the refraction of light, thus accurately hitting the target. Because the shooting fish's feeding method is very strange and interesting, residents in east indies and Polynesia like to keep the shooting fish in glass jars and watch its wonderful "shooting" performance. They put a wooden stick in the fish tank, put a thorn on the exposed end, and then put a live insect on the thorn. When the archer fish who is playing in the water sees a living small animal, it will shoot two water bombs in a row according to the small insect's "sudden" and "sudden", and the insect will fall into the water, only to see the archer swallow the insect happily and play freely again.
