Goldfish Eye Diseases

There are many issues that can be problematic for your fish. Many of these can involve the eyes. The following conditions are caused by multiple things including: bacterial infections, fungal infections, parasites, viruses and of course trauma. Depending on the cause, there are different types of medications and bath treatments that can help. Some issues might lead to a loss of the injured eye but don’t be overly concerned because goldfish are hardy and can live quality lives with limited or even no vision.

Blind Goldfish

Many serious goldfish eye injuries can heal, even if it causes them to go blind. A goldfish with a missing eye can live out its life without any issues. Even if it is completely blind, it can still sense its surroundings by using its lateral lines, sense of hearing and sense of smell. To feed a blind goldfish, try using sinking pellets so the blind goldfish can feel around on the substrate to find its food. Make it a habit to feed the goldfish in the same location in the tank or pond to maximize the chances of the blind goldfish finding food.
