The you see a fish off to your right is actually farther to the left in the direction you’re looking due to refraction of light.
Refraction of light is the bending of light rays as the cross the boundary between two media of different densities.
When light travels from a less dense to a denser medium, the ray of light is bent closer towards the normal. However, when the ray of light is travelling from a denser to a less dense medium, the ray of light is bent away from the normal.
Considering the situation in seeing a fish through an aquarium. Light rays from the water which is less dense than air travels to the eyes and is bent away from the normal. Therefore, the fish seen straight ahead is actually, farther to the left.
In conclusion, refraction of light causes the apparent change in the position of the fish.
