01. Ichthyophthirius multifiliis
This is a highly contagious protozoan disease that causes white spots on the body and fins of infected fish. The spots are actually the parasite’s egg sacs, containing hundreds of parasites.

The best way to prevent ich in black moors is to maintain a stable environment for your fish and quarantine new fish before introducing them to your tank.
02. Costia necatrix
This protozoan parasite is a rare cause of goldfish diseases. It can cause several symptoms, including lethargy, loss of appetite, abnormal swimming, and white patches on the body and fins.
Costia is treated with a medication called Acriflavine, which is available from most pet stores. You can also treat your fish with copper.

When infected with fish lice, black moor goldfish will become restless, clamped fins, and stop eating. Fortunately, you can easily treat fish lice by picking off the lice with a pair of tweezers or using potassium permanganate.
05. Anchor worms
Anchor worms are another parasite that can infect black moor goldfish. These worms are long (about 1/2 inch) and thin and have a small hook at the end.
The anchor worm buries its head under the fish’s skin and feeds on the blood. These worms develop in the muscle of the fish for several months, release eggs and then die.
Once the worm is dead, the remaining hole looks ugly and can become infected.
You can easily identify anchor worms by their long, thin body and a small hook at the end. To treat anchor worm infections, you have to bath the infected fish in a potassium permanganate solution for 10 to 30 minutes.

Dropsy is a serious bacterial infection that can cause the fish to swell up and look bloated. In severe cases, the scales on the fish will stand out from the body, and the fish will die.

But you can try treating your fish with Kanamycin and Vitamin B6 for 30 days.
11. Tail rot/ fin rot
Tail rot and fin rot are caused by a number of different bacteria, including Aeromonas, Pseudomonas, and Mycobacterium.
These bacteria can cause extensive damage to the fins, tail, and body of the fish.
Symptoms of tail rot and fin rot include redness and inflammation around the fins and tail, fraying or rotting of the fins and tail, and sores on the body. In severe cases, the fish may lose its tail or fins completely.
Tail rot and fin rot are treated with antibiotics, but you should also clean the tank and remove any sick or stressed fish to prevent the spread of the disease.
Goldfish are also prone to fungal infections, which can cause the fish to lose its appetite, swim abnormally, and develop sores on the body.
