Melon Butterflyfish (Chaetodon trifasciatus) | Digital Marine Atlas

The Radiant Indian Ocean Melon Butterflyfish

The Melon Butterflyfish (Chaetodon trifasciatus), also known as the Indian Redfin Butterflyfish, is a vividly patterned coral‑reef butterflyfish found across the tropical Indian Ocean. With its soft lavender‑blue upper body, glowing yellow‑orange chest and fins, and fine pin‑striped lines sweeping across its flanks, this species creates a striking contrast as it glides above living coral. It naturally inhabits coral‑rich lagoons and semi‑protected seaward reefs, where pairs patrol established territories and pick delicately at coral surfaces.
