Ich (Ichtyopthirius): This is one of the most common diseases. This is a type of parasite which attaches itself to a stressed goldfish. Then they feed off of the fish. They look like little shiney stars on the goldfish. They will fall off in a day or two and will lay eggs, which will then start the process over again.

bacterial infection that starts after the fish is already weak. The fin will start rotting away, looking like it was torn.
