Common name: surgeonfish

General information

The Black Surgeonfish, also known as the Black Tang or Gem Tang, is a striking marine fish that is highly sought after by aquarists for its sleek, velvety black body and contrasting bright white or blue horizontal lines. It is a member of the Acanthuridae family, which is known for the distinctive 'scalpel' located on the caudal peduncle, used for defense and territorial disputes.

Care

The Black Surgeonfish requires a spacious aquarium with plenty of swimming room and a well-established environment with stable water conditions. They are herbivorous and thrive on a diet rich in marine algae and vegetable matter. It's important to provide them with ample grazing opportunities to prevent malnutrition and to maintain their immune system.

Reproduction

In the wild, Black Surgeonfish are known to form spawning aggregations, but breeding them in captivity is quite challenging. They release eggs and sperm into the water column, where fertilization occurs. The larvae are planktonic before settling down and transforming into juveniles.

Habitat

Native to the Indo-Pacific region, the Black Surgeonfish can be found in clear lagoons and seaward reefs, often in areas with strong currents. They are typically solitary but can occasionally be seen in small groups. In the aquarium, they require a habitat with plenty of live rock for grazing and hiding spots.
