There is no treatment for this disease.
Breeding of Shubunkin Goldfish
It is easy to breed Shubunkin Goldfish. All they require is the right water conditions. Shubunkin will spawn in the right conditions, which means that if you ensure that the tank conditions are ideal, the fish will reproduce naturally.
To breed them you will have to set up a breeding tank. The tank must be of a 20-gallon size and add plants where the females will spawn. You can add artificial plants as well. You can also separate the males and females for some days before breeding.
Temperatures can be gradually decreased to roughly 60° F (11° C) to stimulate spawning, then gradually warmed at a rate of 3° F every day until they spawn.
When the temperature is between 68° and 74° F, spawning begins. High-protein meals, such as brine shrimp or bloodworms, should be fed to them in large quantities.
For a few days, males may begin to chase females in a non-aggressive manner, and their colors may darken. Males will then force females against plants, causing the females to release eggs, which the males will fertilize.
Spawning can take as little as a few hours and generate as many as 10,000 eggs. As the spawning ends, immediately remove the parent fishes from the tank. Otherwise, they will begin to eat the eggs.
Depending on the temperature, the fertilized eggs will hatch in 4 to 7 days. Until the newly hatched goldfish are big enough to consume flake or brine shrimp, you can give them fry meals, or you can feed them the same food as the parents as long as it is crushed extremely fine.
The fry is initially a dark brown or black hue to help them hide and avoid being eaten by larger fish. After a few months, they develop their adult color and can be introduced to larger fish until they reach approximately 1 inch in length.
