How good of vision do fish have?
Biologists believe that their depth perception is poor and most fish have a semi-blind spot straight ahead of them. To compensate for this, the retina of their eyes is slightly extended. This is where the term „fish eye“ lens comes from. Fish generally have excellent close up vision, but poor distance vision.16.03.2012
What does a fish’s eyesight look like?
Fish eyes are similar to the eyes of terrestrial vertebrates like birds and mammals, but have a more spherical lens. Birds and mammals (including humans) normally adjust focus by changing the shape of their lens, but fish normally adjust focus by moving the lens closer to or further from the retina.
Do fish get happy when they see you?

How do I play with my pet fish?

Why does my fish stare at me?
Your betta fish may be staring at you because they are hoping for some food, curious about your movements, watching you for entertainment, or just gazing off into the distance. If your betta is constantly lethargic and often motionless, however, then they may not be as happy and healthy as they should be.
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.

What do fish do all day in a tank?

Do fishes sleep or not?
While fish do not sleep in the same way that land mammals sleep, most fish do rest. Research shows that fish may reduce their activity and metabolism while remaining alert to danger. Some fish float in place, some wedge themselves into a secure spot in the mud or coral, and some even locate a suitable nest.
Do fish have feelings?
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.20.06.2016
