Schooling Blue Chromis over Staghorn Coral and Hydroids in Bali

A wide-angle landscape underwater photograph captures a vibrant reef scene in Bali featuring a large colony of branching staghorn coral (Acropora species) swarming with neon-blue damselfish (Chromis viridis). To the right, feathery brown hydroid plumes stand tall on the reef structure, while small yellow, green, and blue damselfish scatter across the open blue water column above. Below the main branching coral, small brain corals, encrusting sponges, and finger corals form a complex benthic foundation. The composition captures the dynamic movement, vivid color contrast, and rich biodiversity typical of healthy Indonesian reef ecosystems. Ideal for marine biology textbooks, coral reef biodiversity studies, ocean conservation campaigns, and professional nature stock media.
