It dosent use refraction it allows for it, it shoots down its prey with water droplets from under water so it must cope for refraction and somehow it can, that's why its an amazing fish its because it can calculate the level of refraction and cope with it.
Most common microscopes are of the refracting type i.e You see the object via the large lense above the object, where it is magnifed by the more powerful lense which to eye(s) look through. Some are of the reflectiong type as are telescopes. The immage of the object to be viewed is sent to a flat mirror where it is then sent to the more powerful eye piece.
In general, the process refraction only occurs in the eyes (as far as I know). So I assume you are asking how animals use refraction in their eyes, and by "refraction" you mean the refraction of light. In general, when light enters the eyes, it first enters the cornea of the eyes, which is then refracted into the pupil through the aqueous humor. The thickness and convexity of the lens control how the light is refracted into the eye. The light is focused on the retina which has rods and cone (photoreceptors/light sensors) which sends nerve impulses to the brain. Therefore, the animal is able to see. The parts of the eyes that does the refraction are the cornea, aqueous humor, lens, and the vitreous humor. You might want to surf the web for more details about this
There are only a few other predators that will eat an archerfish. The predators that eats an archerfish are the whelps, olay, and the stairwell phaert.
It uses its mouth.
from its booty
They swim directly beneath an insect, hovering under the prey, where the light refraction is the least. However, experimentation has shown that the Archerfish can hit prey at greater angles than a perpendicular angle without losing accuracy. When an archerfish selects its prey, it focuses its eyes on it and sticks its snout just above the surface, squirting a jet of water at its victim. It does this using the narrow groove that is formed in the roof of its mouth. It presses its tongue against this groove to form a narrow channel, then contracts its gill covers to force a powerful jet of water through the channel. The resulting jet of water can be up to 2-5 m long, but their accuracy only allows them to shoot insects 1-1.5 m away. The fish can alter the power of the shot for prey of different sizes. If the first shot does not knock the victim into the water, the archerfish will keep trying. Source: wikipedia.com
In the wild archer fish can grow up to 12" long, although in aquariums they tend to vary usually smaller.
Smallscale archerfish was created in 1860.

A banded archerfish is an archerfish, Latin name Toxotes jaculatrix, known for its ability to spit out a jet of water to shoot down its prey.
bats and dolphins use sound refraction to hunt for food. the bat is blind so they have to use sound refraction.

An archerfish is any of the species o fish in the Toxotidae family, who prey on small animals near to the surface of water by shooting them with water from their mouths.

The species in the genus Toxotes (Archerfish) all occur in fresh, brackish, and marine deep pool like waters from India to the Philippines, Australia, and Polynesia.
