Common name: Thompson's Surgeonfish
General Information
The Thompson's Surgeonfish, scientifically known as Acanthurus thompsoni, is a striking species found in the tropical waters of the Indo-Pacific region. While not as commonly seen in the pet trade as some other surgeonfish, its unique appearance and moderate care requirements make it a desirable addition for experienced aquarists.
The Thompson's Surgeonfish plays an important role in the hobbyist community, often sought after for its ability to control algae in reef tanks. Its grazing habits help maintain the balance of the aquarium ecosystem, making it a functional as well as an aesthetic choice for marine enthusiasts.

Care
Caring for the Thompson's Surgeonfish requires a well-established marine environment with plenty of swimming space. These fish are active swimmers and need a tank that allows them to roam freely. A tank of at least 500 liters (130 gallons) is recommended to accommodate their size and activity level.
Providing a variety of hiding spots and live rock structures will help replicate their natural habitat and offer security. These fish thrive in stable water conditions with efficient filtration and moderate water flow.
Diet and Feeding
In the wild, Thompson's Surgeonfish are primarily herbivorous, grazing on algae and detritus. In captivity, they should be offered a diet rich in marine-based algae, supplemented with high-quality flake and pellet foods. Occasional treats of frozen mysis or brine shrimp can provide additional variety and nutrition.
Feeding should occur multiple times a day to mimic their natural grazing behavior. Ensure that the diet is well-rounded to prevent nutritional deficiencies and support their vibrant coloration.
Behavior and Compatibility
Thompson's Surgeonfish are generally peaceful but can exhibit territorial behavior, especially towards other surgeonfish. They are best kept with a mix of other peaceful species to minimize stress and aggression.
These fish are reef-safe and can coexist with a variety of invertebrates and corals. However, care should be taken when introducing them to tanks with other algae-grazing species to prevent competition for food.
Health and Common Issues
With proper care, Thompson's Surgeonfish can thrive in captivity. They are susceptible to common marine diseases such as ich, so maintaining optimal water quality and providing a stress-free environment is crucial.
Regular observation and quarantine of new tank additions can help prevent the spread of disease. A balanced diet and stable conditions will promote a long and healthy life for these fish.
Habitat
The Thompson's Surgeonfish is naturally found in coral reefs and rocky substrates across the Indo-Pacific, from the Red Sea and East Africa to the Hawaiian Islands. They prefer warm, clear waters with abundant algae, which forms the bulk of their diet.
