Stegastes nigricans
S. nigricans are found naturally in and around coral reefs. Adult S. nigricans live in reef flats and lagoon reefs in colonies in areas with staghorn coral. S. nigricans are limited by water temperature and their diet and have been experiencing a negative impact of their population amounts. Climate and ocean composition has been changing due to global warming and fossil fuel use, therefore this habitat is being altered and coral reefs are becoming greatly reduced.
