Studies have found that fish see objects placed outside their tank.
How good is fish eyesight?
Fish retinas generally have both rod cells and cone cells (for scotopic and photopic vision), and most species have colour vision.
Some fish can see ultraviolet and some are sensitive to polarised light
. Among jawless fishes, the lamprey has well-developed eyes, while the hagfish has only primitive eyespots.
What do fish see from inside the aquarium?
Looking straight on, the fish also sees through, but due to the physics of light and its transition through air/water and in this case the intermediary glass,
the fish sees only through a circle while everything around that circle reflects
. In fact, if we go underwater, we can see a similar effect up at the surface.
How far fish can see?
Standing next to one in a dense fog, you can make out every detail of its bark. “Fish live in perpetual fog, sometimes thin, sometimes thick. Our visual field can extend miles on a clear day, but in the clearest waterway, maximum visual distance is
100 to 150 feet
and that's rare.
Can my fish see me?
Yes they can
. My chiclids often swim up and down when they see me because they know I'm their source of food. But they hide away when my brother or sister enter because seeing more than one person sometimes scares them. They also like to stare at me when I stare at them to look for infections or whatever.
Can fish see clearly underwater?
Science tells us that fish have eyes similar to humans, but
they also have protective film over their eyes so that they can see more clearly underwater
. Their eyes have rod and cone cells on their retinas, so we know that they can see color as well as in shades of grey, light and dark.
Can my fish hear me?
However,
yes, they can hear your voice
.
They just know someone is speaking. They can associate sounds with action, though. For example, if you are to say your betta fish's name – let us call him George – each time you sprinkle food in his aquarium, he will eventually associate the sound of “George” with food.
Why do fish stare at me?

Why does my fish stare at the glass?
Fish exhibit many behaviors that tell us how they are feeling, and glass surfing (also known as pacing) is one of them. This is when fish constantly swim up and down the sides of the aquarium glass.
One reason they do this is stress
. It could mean they aren't happy in their environment, for one reason or another.
What color is hardest for fish to see?

a multi-colored line that blends into the background
should be harder for fish to see and track. While red and green blend well in many situations, blue blends best in offshore waters.
What color do fish see?
The goldfish has four kinds of cones:
red, green, blue and ultraviolet
. Other fish have different numbers and kinds of cones meaning that they have the capability of seeing in color. However, simply finding cones in the eye does not mean that an animal has color vision.
How well can fish see in dark?
Fish living in the deep sea manage to navigate in complete darkness. It's not strictly ‘seeing' but fish have rows of pressure-sensitive organs running down each side of their body called the lateral line, which allows them to sense nearby animals from the pressure changes in the water.
What color do fish see best?
In low light or at night, colors matter less, because fish then rely more on the rod cells in their eyes, which detect contrast and movement but not color.
White
, offering the greatest contrast, might well be the color of choice in such situations.
Are fish near or farsighted?
Fish have been described as being
nearsighted
, and can probably focus on objects much closer to their eyes than humans can.
Do fishes feel pain?
CONCLUSION. A significant body of scientific evidence suggests that
yes, fish can feel pain
. Their complex nervous systems, as well as how they behave when injured, challenge long-held beliefs that fish can be treated without any real regard for their welfare.
Why do fish follow you?

Do fish think and feel?
Fish Have Feelings, Too
: The Inner Lives Of Our ‘Underwater Cousins' : The Salt Jonathan Balcombe, author of What A Fish Knows, says that fish have a conscious awareness — or “sentience” — that allows them to experience pain, recognize individual humans and have memory.
How do fish see outside of the water?
It looks like a mirror from underneath when looking at an angle
. This effect is caused by sunlight and how much light is reflected back from the bottom in shallower bodies of water. Biologists have a term known as the fish's “window of vision” to the world above the surface. This is almost directly above them.
Can fish see air bubbles?
Air has an extremely low refraction index, making it impossible to see.
Neither us nor fish can see the air in the environment
.
Do fishes cry?
As we mentioned before,
fish cannot cry
because they lack the part of the brain which allows mammals to produce tears. This part of the brain is called the cerebral cortex. Besides, fish lack both the emotional depth and mental complexity to be able to cry.
