Half-and-half chromis swimming over bleached Finger and Fire corals

Bleached Coral Reefs in Clear Seas.

In this underwater footage, a large school of half-and-half chromis fish swims over a coral reef dominated by bleached finger and fire corals. The corals, primarily white and pale yellow, show signs of stress, covering the reef in their skeletal-like branches. The finger corals extend upwards, while the fire corals add varied texture to the scene with their mound-like shapes. The half-and-half chromis, small black and white fish, are scattered throughout the frame, darting swiftly through the reef. The video clip showcases the ongoing life of marine species despite the bleached corals that surround them.

Half-and-half chromis, known for their unique two-toned coloring, are small, schooling fish that rely on coral reefs for shelter, breeding grounds, and access to planktonic food sources. Their relationship with coral reefs is symbiotic, as these fish often inhabit branching corals like finger and fire corals, finding protection within their intricate structures. However, coral bleaching has severe implications for chromis populations. When corals bleach, they become weak and lose their structural complexity. This degradation deprives chromis of the shelter and resources they depend on, disrupting their feeding and breeding patterns.
