Answer
Claudia,
The white dots on the back of your Black Moore is Ich. The one in the picture looks like a fungal problem. This is due to bad water quality. It is very important when it comes to goldfish that their water is clean all the time. You can add some aquarium salt to their water. Dissolved 1 teaspoon of aquarium salt to one gallon of water. Make sure the salt is dissolved before you add it to to the water or it will burn him. You can also add a medication fr fungal problems. Jungle is a good brand. Follow the directions on the container and they should be ok.
