Teardrop butterflyfish

The Teardrop butterflyfish (Chaetodon unimaculatus) is a marine species primarily distinguished by its vibrant yellow coloration and a prominent black spot or 'teardrop' on its sides. Native to the Indo-Pacific region, it features a pattern of thin, dark vertical lines on its body and a white margin on its dorsal and anal fins. Despite its striking appearance, it is not among the most popular species in the aquarium hobby, partly due to its specific dietary and care requirements.
