Is there any reliable information on fish's eyesight? I'm curious because when i enter the room most of my fish fly to the front of the glass the Fronts duck behind their fav rocks. Do they react to the movement or do they actually recognize us?
How well do fish see?
- Thread starter cichlid savage
- Start date
the quality of a fishes vision varies from species to species. Our fish from that distance are most likely reacting to the movement with their conditioned response. Whether or not fish recognize us individually, I don't beleive so, but it's fun to pretend.
I agree, i have chiclids and natives that see me coming from 10 feet or more away and recognize me soley i think as a provider of food and go into their happy dance, On the other side of that is the Purple spotted Gudgeon which i have to watch closely because his eyes are so small and beady he cant see the food well enough to go on the attack mode as quickly, So... varys by fish i think >>>what he said 
I just noticed that now im a crayfish, I dont wanna be a crayfish !!!! Is this a Government plot to get me to post More????

Oscars can see pretty well, they're not built for speed, and the combo of this and the murky water they're often found in makes their eyesight important for locating snails and mollusks to eat. Others are nearly blind and rely on scent.
Personally, my fish will haul ass if a stranger enters the room. Most of my Tanganyikans do not beg for food, but have become accustomed to my presence. They don't hide when I approach. I feel they know my mannerisms if not my appearance.

i think it will depend on the fish, for example open water preds such as umbee probably have sharp eyesight and are extremely sensitive to movement but a pleco may not have such great eyesight as it doesnt hunt but it grazes.
im only guessing though by looking at what seem fairly obvious points so i could be wrong.

Fish that see well do recognize people. We did an experiment with an arapaima I worked with. He would only come take food from a select few people. We tried breaking the association with different colored shirts etc.... he could pick out the same people to take food from, and refused to take food from people he "didn't like".
I've had sharks that will only take food from certain people as well, so it is more than just a one time or one species idea.

I know cichlids do react to seeing certain people. If another person comes up to our tanks they dont go crazy if my husband approachs his 125g it loks like a bunch of puppies to their momma my platies and guppies though mind there business the whole time until i actually ang my hand over the tank with food.

i know uaru and blue acaras have good eye sight. the minute the wife or me goes to the freezer they suddently crowd at the front glass watching, then when they see the white tub the go mental cos they know bloodworm is coming. a blue tub has no effect so they have good enough eyesight to identify 2 different tubs at approx 10ft.
