Fish and Coral Reefs (IMAGE) University of Delaware Caption Researchers at the University of Delaware find that butterflyfish avoid coral that has been in contact with seaweed and their change in appetite may be an early warning of trouble for the reef. Their paper, which appeared this week in the Nature publication Scientific Reports, is the first to critically evaluate the impact coral-seaweed interactions will have on coral associated reef fishes, a key component of coral reef resilience.
