School of black tang fish swimming over colorful and bleached corals

Bleached Coral Landscapes.

In this underwater video clip, a school of black tang fish swims in a dense coral reef filled with both bleached and healthy coral species searching for food. The tang fish are dark in color, standing out sharply against the backdrop of corals, creating a dynamic contrast as they move collectively through the scene. Their smooth, rounded bodies and extended fins are clearly visible as they forage the diverse coral formations. The coral reef in this footage features a mix of species, with some corals bleached white while others retain shades of brown, orange, and light blue, showing signs of resilience.

Tang fish, known for their striking colors and streamlined bodies, are vital inhabitants of coral reef ecosystems. Often feeding on algae, they play a crucial role in maintaining the reef’s balance by preventing algae overgrowth, which can suffocate corals. Black tangs, like those seen in this footage, rely on healthy reefs not only for food but also for shelter, finding protective crevices among coral structures. Their symbiotic relationship with coral reefs is essential for both the fish and the reef, as the tangs help sustain the ecosystem’s health by keeping algae levels in check. However, coral bleaching poses a serious threat to this delicate balance.
