By nature the goldfish is a fast learner and will make a loving fish pet in your aquarium, they are an intelligent type of fish and can recognize their keepers.
In the wild, they are trouble makers from eating the larvae and eggs of the long-toed salamander to making the water too dirty for other aquatic animals to feed.

However, if you see your goldfish displaying some aggressive behavior, it is probably because of stress or sickness caused by inappropriate living conditions or poor water quality. Goldfish are, however, suitable for a community tank and in the excerpt below we will explore some of the likely fish that can be paired with your goldfish.
