Blue lined surgeonfish Profile

The Blue lined surgeonfish (Acanthurus nigroris) features a sleek body predominantly dark in color with vivid blue lines that stretch from head to tail, providing a striking contrast. Originating from the central and western Pacific Ocean, this fish is characterized by its distinct appearance and the sharp spine near its tail, typical of surgeonfish. Despite its attractive looks, it is not among the most popular in the aquarium hobby, partly due to its specific care requirements and size.
