General Description
The Doctorfish belongs to the Acanthuridae family, specifically the Acanthurus genus. These Surgeonfish are known for mimicking juvenile Angelfish as a defense mechanism against predators, making them challenging to differentiate from adult fish. They primarily feed on various types of algae and have a caudal fin scalpel for self-defense.
Aquarium Suitability
With suitable care, Doctorfish are recommended for aquariums, although they have higher demands regarding tank size, surroundings, and water quality compared to fish in the Zebrasoma genus. They require a minimum tank size of 2000 liters and thrive in a well-established aquarium with ample space for swimming and hiding places, particularly when newly introduced.
Care and Hardiness
The hardiness of the Doctorfish species is currently unknown, but they are generally known to be algae eaters, necessitating a diet rich in algae-based foods to maintain a healthy immune system. Regular feeding and supplementation with algae-rich foods are crucial for their well-being.
Reef Suitability
Doctorfish are considered reef-safe and rarely bother corals or invertebrates, except for larger species like Palettes/Blue tangs. They do well in coral aquariums as they assist in keeping the tank free from algae.
Aquarium Setup
For setting up an aquarium for Doctorfish, it is essential to have a well-run system with sufficient algae on rocks and stones for grazing. Maintaining water conditions within the ranges of pH 8.1-8.4, temperature between 22.2-25.6°C, and specific gravity of 1.020-1.025 is recommended.
Behaviour
These Surgeonfish spend most of their time swimming around and nibbling on algae. They are not typically aggressive towards other fish but may display aggression when establishing a hierarchy if multiple species are present. Adequate hiding places and individual sleeping areas are essential for minimizing stress and aggression.
Feeding and Diet
Doctorfish primarily feed on macroalgae like seaweed/nori and microalgae such as spirulina. Maintaining a diet rich in algae-based foods is crucial for their overall health and immune system.
Dimorphism and Captive Reproduction
Information regarding dimorphism and captive reproduction of Doctorfish under controlled conditions is not provided.
Habitat and Distribution
Doctorfish, specifically the Acanthurus chirurgus species, are found in the Mexican Gulf in the West Atlantic region. They inhabit areas with abundant algae for grazing, making them vital for coral reef ecosystems.
