Common name: coralfish

General information

The Orangefin Anemonefish, scientifically known as Chelmonops truncatus, is a vibrant and captivating species popular among marine aquarium enthusiasts. This species is distinguished by its bright orange fins and the unique truncated tail from which its name is derived. It is closely related to the well-known clownfish and shares many of the same appealing characteristics that make clownfish a favorite in the hobby.

Care

Caring for Orangefin Anemonefish requires an established aquarium with plenty of hiding spaces and a stable environment. They thrive in a tank with live rock formations and benefit from a varied diet that includes both meaty foods and algae-based feeds. Consistent water quality and parameters are crucial for the health of these fish.

Reproduction

Like many anemonefish, Chelmonops truncatus exhibits protandrous hermaphroditism, where individuals have the ability to change sex from male to female. They form monogamous pairs and exhibit parental care, with the male actively tending to the eggs until they hatch. Breeding in captivity can be achieved with careful attention to water quality and feeding.

Symbiosis

Orangefin Anemonefish have a symbiotic relationship with sea anemones, similar to other clownfish species. They benefit from the protection provided by the anemone's stinging tentacles and, in return, offer the anemone food scraps and enhanced water circulation. This mutualistic relationship is fascinating to observe in a home aquarium.

Habitat

Chelmonops truncatus is found in the Western Pacific, inhabiting coral reefs and lagoons. They prefer areas with a rich growth of anemones, which serve as their protective hosts. In the wild, they are typically associated with specific species of anemones, but in captivity, they may adapt to other suitable hosts.
