The cause of blindness in freshwater fish is frequently sought by owners of fishing waters and fish farmers. The blind fish can lose sight in one eye due to growth behind the eyeball, or they can lose sight in both eyes because of an accident. In some cases, the blindness is caused by a bacterial infection of the retina. In the case of freshwater fishes, there are several factors that can lead to blindness.

This may help the blind fish avoid predators, the researchers said.

It’s possible that a betta fish isn’t eating pellets because they are not hungry. If a betta is being overfed, this is often the case. Bettas have small stomachs, so they only need four to six pellets twice a day, or the equivalent in live, frozen, and canned foods.
If a fish does not eat at all, there are a few things that can be done to help it. One is to give the fish a small amount of food every few hours to keep it from getting too full. Another way to do this is by giving it a little bit of water every couple of hours.
If the water is too hot or too cold, the bettas will not be able to digest it properly and will become dehydrated, which will cause them to become lethargic and lose their appetite. You can also give them water that is slightly acidic, such as lemon juice or vinegar, as this will help them digest their food and keep them hydrated.

How do cave fish see?
The mexican blind cavefish has no eyes, but it can see obstacles by puckering its mouth. This is the first time that this form of navigation has been described. The study, published in the Journal of Experimental Biology, was led by researchers at the National Autonomous University of Mexico (Universidad Nacional Autónoma de México) and the Universidad de los Andes (UNAM) in Mexico City.
It was funded by the Natural Sciences and Engineering Research Council of Canada (NSERC), the U.S. National Science Foundation, the Canadian Institutes of Health Research (CIHR), and Mexico’s National Institute of Anthropology and History (INAH) under the auspices of the Mexican Ministry of Science, Technology and Innovation (MOSTI). The work was conducted in collaboration with researchers from the Instituto de Investigaciones Científicas y Tecnológicas (Iniciativas de Ciencias Naturales) at UNAM, as well as the Center for Evolutionary Biology (CEB) of INAH.
