General Description
The Ocean surgeon, also known as the Brown surgeonfish, belongs to the Acanthuridae family and is part of the Acanthurus genus. This species is known for its mimicry of various Angelfish as juveniles to evade predation, making adult identification a challenging task.
Aquarium Suitability
Ocean surgeons place higher demands on tank size, surroundings, and water quality compared to other fish species. They require a well-established aquarium with ample space for swimming and hiding places, especially when newly introduced.
Demands, Care, and Hardiness
With an average level of hardiness, Ocean surgeons have a peaceful temperament, making them suitable for aquariums with proper care. They thrive in water conditions with ideal parameters of pH (8.1-8.4), KH (8-12), salinity (1.020-1.025), and temperature (22.2-25.6°C).
Reef Suitability
The reef compatibility of Ocean surgeons is unknown, so caution is advised when considering them for a reef aquarium setup.
Aquarium Setup
To accommodate Ocean surgeons, a minimum tank size of 2000 liters is recommended. The aquarium should be well-maintained with plenty of algae-rich rocks and stones for grazing. Supplementing their diet with macroalgae like seaweed and microalgae such as spirulina is essential.
Behaviour
In an aquarium setting, Ocean surgeons spend their time swimming around and nibbling on algae. They are generally peaceful towards other fish species but may establish a hierarchy when multiple surgeons are present.
Feeding and Diet
Ocean surgeons primarily feed on small crustaceans like krill, mysis, and artemia. Maintaining a diet rich in algae-based foods is crucial for their immune system and overall health.
Dimorphism
Dimorphism within this species is not highlighted, and details on captive reproduction are not provided.
Habitat and Distribution
Ocean surgeons are found in the Western Atlantic, ranging from Massachusetts, USA, to Bermuda and Brazil. They are also present in the Eastern Atlantic around Ascension, St. Helena Islands, and off Angola. These fish primarily inhabit regions with a good supply of algae for sustenance.
