Most fish never blink because they don't have eyelids.
Fish do not have eyelids like humans do, so they cannot blink in the same way. However, some fish have a nictitating membrane that can cover their eyes for protection. This membrane acts like a thin, transparent eyelid and helps keep the eye moist.
They don't have eyelids and the reason why people blink is because we have to wet our eyes,but, they live under water so they're eyes are always wet.
No eyelids

No, perch do not blink, humans have to blink to give mosture (a little bit of water) to thier eyes, but perch practicly live in mosture, so therefore they do not need to blink so they dont, that is the same with all fish.
A fish that can blink with both eyes is the four-eyed fish. Although its name suggests that it has four eyes, it actually only has two eyes like other fish, but each eye is divided in two parts allowing it to see above and below the water simultaneously.
it is impossible because fish never blink ^^true but i won by forefit^^ HEHAHE
No, no fish can blink because they have no eyelids. We blink to regain moisture in our eyes and wash away dirt, but they are surrounded by moisture and water, so there is no need to blink. However, the are a few that have a nictitating membrane (also called the third eyelid) that they "blink". This "third eyelid" is used to protect the eyes.
no fish have eyelids. That is why fish don't blink.
