Common name: Bluelined surgeonfish
General information
The Lined Surgeonfish, scientifically known as Acanthurus lineatus, is a vibrant and active member of the reef community. It is easily recognized by its striking blue and yellow horizontal stripes, which run across its body and extend into its fins. This species is also known for the distinctive 'surgeon's scalpel'—a sharp spine on the caudal peduncle used for defense.
Acanthurus lineatus is a herbivorous fish that plays a significant role in controlling algae growth on the reef. It is a popular choice among aquarists due to its bold colors and dynamic swimming behavior.

Care
The Lined Surgeonfish requires a spacious aquarium with plenty of swimming room and a well-established live rock setup to mimic its natural habitat. It is essential to maintain high water quality and stable conditions, as this species can be sensitive to fluctuations in water parameters.
A diet rich in marine algae and vegetable matter is crucial for the health of Acanthurus lineatus. Supplementing with high-quality dried seaweed and algae-based pellets or flakes will help maintain its vibrant coloration and provide necessary nutrients.
Reproduction
In the wild, Lined Surgeonfish are known to form spawning aggregations. However, breeding them in captivity is challenging and rarely successful. They exhibit broadcast spawning, where eggs and sperm are released into the water column.
Habitat
Acanthurus lineatus is found in the Indo-Pacific region, from East Africa to the central Pacific, including the Great Barrier Reef and Hawaii. It inhabits coral reefs and lagoons, often in clear, current-swept channels at depths ranging from shallow waters to about 15 meters.
This species is often seen grazing on algae-covered substrates and is an essential part of the reef ecosystem, contributing to the balance and health of coral reefs.
