Workers at a large aquarium in Las Vegas feed many sharks and fish in a big tank. The aquarium has thousands of animals. The sharks eat fish like mackerel and sardines. The food helps them stay healthy. Visitors can watch the feeding time and see how the animals move in the water. Many people come to the aquarium to see these animals and learn more about them. The workers watch the animals during feeding time. This helps them know if the animals are doing well. If a shark does not eat, it may need help. The aquarium also works to protect some animals and support ocean life. These activities help people understand why marine animals are important and how they can be cared for properly.
