Common name: Monrovia Surgeonfish
General Information
The Monrovia Surgeonfish, scientifically known as Acanthurus monroviae, is a striking member of the Acanthuridae family. This species is notable for its vibrant blue body accented with a yellow tail and a sharp, scalpel-like spine on the caudal peduncle, which is a characteristic feature of surgeonfish. While not as commonly seen in the aquarium trade as some of its relatives, the Monrovia Surgeonfish is appreciated by hobbyists who seek a unique and visually captivating addition to their marine tanks.
In the wild, these fish are known for their role in controlling algae populations, making them valuable for maintaining the health of coral reefs. Their presence in home aquariums can similarly aid in algae management, though they require specific care to thrive in captivity.

Care
Monrovia Surgeonfish require a spacious aquarium with plenty of swimming room and live rock for grazing. They are best suited to aquarists with some experience, as they have specific dietary needs and can be sensitive to changes in water quality. A tank of at least 300 liters is recommended to accommodate their active swimming habits and to provide a stable environment.
Diet and Feeding
As herbivores, Monrovia Surgeonfish primarily feed on algae in the wild. In captivity, their diet should be supplemented with high-quality marine algae, spirulina, and occasional treats of mysis shrimp or other marine-based proteins. Regular feeding with a variety of foods will ensure they receive all necessary nutrients and help maintain their vibrant coloration.
Behavior and Compatibility
Monrovia Surgeonfish are generally peaceful but can become territorial if space is limited or if housed with other surgeonfish. They are best kept with similarly sized or larger tank mates that are not overly aggressive. Providing ample hiding spots and maintaining a stable social environment can help reduce stress and aggression.
Health and Common Issues
These fish are relatively hardy but can be prone to common marine diseases such as ich, especially if stressed. Proper quarantine procedures for new additions and maintaining excellent water quality are essential to prevent outbreaks. Regular monitoring and prompt treatment of any health issues will help ensure a long and healthy life for the Monrovia Surgeonfish.
Habitat
The natural habitat of the Monrovia Surgeonfish includes the rocky and coral reef areas of the Eastern Atlantic Ocean, particularly around the coasts of West Africa. They are typically found at depths ranging from 5 to 50 meters, where they graze on algae-covered substrates. Replicating this environment in captivity involves providing plenty of live rock and ensuring stable water conditions with moderate flow.
