Popeye Disease
Popeye disease is typically a sign of an underlying health issue. It occurs when fluids build up behind or in the eye. This causes the fish’s eyes to look like they’re popping out of their sockets. If your fish’s eyes appear enlarged in this manner, remove any sharp objects from the tank and isolate them from any aggressive fish.
The problem could be a bacterial infection. Change 30 to 50 percent of the water in the aquarium and treat it with an antibacterial solution. Other causes of the disease are fights between fish and poor water quality.
Bacterial Infections
After parasites, bacterial infections are the most common ailment that goldfish suffer from. Signs of a bacterial infection are cloudy eyes, bleeding, open wounds, white film on the fins or body, and ulcers on the head.
The main cause of bacterial infections is prolonged exposure to dirty water. Such an environment can weaken your fish’s immune system and make it more susceptible to developing infections. A low-quality diet can make your fish sick as well. Antibiotics are needed to cure the infection. You can get a prescription from your veterinarian.
Fungal Infections
When a fungal infection is present, fish will have fuzzy or cottony spots on their bodies. Fortunately, fungal infections are not contagious and are not as common as bacterial infections or parasites. But they do call for immediate medical attention. Generally, they are caused by infected food, poor water quality, or open wounds. A prescription for antifungal drugs from your veterinarian will be needed.
