General information
The Paletail Unicornfish, scientifically known as Chlorurus troschelii, is a distinctive species recognized by its unique morphology. It has a protruding forehead and a characteristic tail shape from which it gets its common name. This species is part of the surgeonfish family, which includes tangs and unicornfishes, known for their vibrant colors and the scalpel-like spines on either side of the caudal peduncle, used for defense.

Care
Paletail Unicornfish require large aquariums due to their size and active swimming behavior. They are herbivorous and thrive on a diet rich in marine algae and vegetable matter. It's important to maintain high water quality and stable parameters to keep these fish healthy. They are generally peaceful but can be territorial with conspecifics or similar-looking species.
Reproduction
In the wild, Paletail Unicornfish are known to form spawning aggregations. However, breeding them in captivity is challenging and rarely successful. They are broadcast spawners, releasing eggs and sperm into the water column where fertilization occurs.
Habitat
Chlorurus troschelii is found in the tropical waters of the Indo-Pacific region, from the Red Sea to South Africa and eastward to the central Pacific. They inhabit coral reefs and lagoons, often seen grazing on algae. They can be found at depths ranging from shallow waters to about 30 meters.
