He Wants To Play
Fish are naturally playful creatures. They love to roam around and hide. When a fish swims in circles, it could be that it is just playing around or having an exercise.

They Want To Stay Put
Fishes often swim as a group referred to like school. Sometimes, a school of fish moves in a certain place in a circular motion simply because they want to stay in that place. Maybe that area has food or some tourist spot or object they find as fun. Swimming in circles may indicate that the school of fishes wants to stay put in a certain area. In this case, you do not have to worry again.

Fishes are natural prey also. They could be attacked by predators like sharks and other bigger fishes. It would be better for these fishes to swim as a group so to lessen the chance of getting eaten by predators. When these schools sensed danger, swimming in circles can be a part of their survival techniques.
He Is Poisoned
If you noticed that your fish is or are swimming in circles constantly for a long time, it might indicate that something is wrong. Try to check the water quality, pH, ammonia, and nitrite levels. If the motion is jerky, rapid, and panicky, the fish might be having an ammonia poisoning.

If your fish is continually swimming in a circular motion, it could also be caused by a parasite. The fish may have gotten a whirling disease wherein a parasite has attached himself onto the equilibrium organ of the host. Also, observe if the fish would rub himself against something then swim away. It could be that an external parasite is living with him.
