Chelmonops truncatus, commonly referred to as the Australian Butterflyfish, is a captivating species native to the coastal waters of Australia. This small butterflyfish variant is prized for its distinctive markings and elegant swimming behaviour, making it a sought-after addition to marine aquariums.

Care Level: Moderate to advanced. This species requires stable water parameters and a well-established tank.

Temperament and Compatibility: Generally peaceful but can be territorial towards conspecifics. Best kept singly or as a mated pair in a community tank with non-aggressive species.
