How do eels affect corals?

Eels play a vital role in coral reef ecosystems by helping to maintain the balance of marine life. They contribute to controlling populations of smaller fish and invertebrates that can overgraze algae, which, if unchecked, may outcompete corals for space and resources. Additionally, eels provide nutrients to the reef through their waste, which can promote the growth of coral and associated organisms. Overall, their presence supports the health and biodiversity of coral reefs.
