Frequently Asked Questions
What is the black spot on my goldfish?
The black spot on your goldfish is likely a sign of ammonia poisoning or a fungal infection. Ammonia poisoning occurs when there is a buildup of ammonia in the tank, which can cause black spots to appear on the fish’s body. Fungal infections, on the other hand, can cause black or gray patches to form on the fish’s skin.
Is the black spot contagious to other fish?
The good news is that the black spot caused by ammonia poisoning is not contagious to other fish. However, if the black spot is caused by a fungal infection, it can be contagious to other fish in the tank. It’s essential to quarantine the infected fish and treat the tank with an anti-fungal medication to prevent the infection from spreading. (See Also: Do Goldfish Lose Their Color)

Add an ammonia-removing product to the tank, and consider upgrading your filtration system. If the black spot is caused by a fungal infection, you’ll need to treat the tank with an anti-fungal medication and quarantine the infected fish.
Can I prevent the black spot from appearing on my goldfish?
