When a fish looks upward at a 45-degree angle, it typically sees the sky. This is because of the refraction of light at the air-water interface, causing the image of the sky to be visible to the fish.

The water exerts an upward force on the fish that partially cancels out the downward force of gravity, making the fish weigh less in water than in air.
