Parrotfish spend 90% of their day cleaning the reef of algae. This cleaning (eating) helps corals grow and thrive, and healthy reefs support more fish in the sea. Parrotfish also contribute to the sand on our Caribbean beaches.

Why did the parrotfish population increase at first and then later decline?

Although I cannot see the graph of the population over time, I am assuming it was exponentially rising and then began to decline. This is because the parrotfish were able to populate only until the species ran out of shelter. Once it ran out of shelter, the exposed fish began to die due to predators or the environment.

How does the feeding activity of parrot fish benefit the health of coral reefs?

Algae-eating parrotfish, like other herbivorous reef fish, play an important role in coral reef ecosystems by removing the algae that compete with corals. They found that coral growth is positively driven by the abundance of parrotfish on the reefs but not affected by sea urchin abundance.
