Answer:
The muscles contract from side to side and front to back. The fish's body pushes against the water and moves the fish forward. Fins help fine-tune swimming. The caudal fin, or tail fin, increase speed.

Answer:Fish swim by flexing their bodies and tail back and forth. Fish stretch or expand their muscles on one side of their body, while relaxing the muscles on the other side. This motion moves them forward through the water.
