Paracanthurus hepatus

Datasheet

General Description

The Blue Tang, scientifically known as Paracanthurus hepatus, is the sole species in its genus and stands out among Surgeonfish due to its unique appearance. Typically peaceful, these fish are often overlooked by other Surgeonfish species due to their distinct characteristics. Blue Tangs exhibit a charming swimming style and can display playful behavior when observed, although they are delicate, especially during transportation.

Aquarium Suitability

Considered suitable for aquariums with caution, Blue Tangs require a peaceful environment with an abundant food supply during acclimatization. These fish mature quickly and, despite seeming to fit in smaller tanks when young, it is not recommended to house them in such confined spaces due to their active nature. Regular access to algae-based nutritional offerings is crucial for maintaining the health of Blue Tangs in captivity.

Demands, Care, and Hardiness

Categorized as delicate, Blue Tangs are sensitive during transportation and acclimatization, emphasizing the need for a well-established tank with algae-rich environments. They thrive in aquariums with hiding spots and expansive swimming space, demonstrating a preference for active movement. As algae eaters, Blue Tangs require a diet primarily based on algae to support their immune system and overall well-being.

Reef Suitability

Reef safe with caution, Blue Tangs can be integrated into reef setups, but larger individuals may exhibit aggression towards corals or invertebrates. Balancing the tank with suitable hiding places can help mitigate any potential conflict, and caution should be exercised when introducing multiple fish of this species into the same tank.

Aquarium Setup

To accommodate Blue Tangs, a minimum tank size of 700 liters with stable water conditions, including a pH of 8.1-8.4, a temperature range of 22.2-25.6°C, and a salinity level of 1.020-1.025, is recommended. Additionally, maintaining carbonate hardness (KH) between 8-12 is crucial for their well-being.

Behaviour

Known for their fun and interesting personalities, Blue Tangs are generally peaceful but may display territorial behavior, especially when sharing a tank with other Surgeonfish. Establishing a hierarchy within the tank is common among multiple fish of this species, highlighting the need for adequate hiding spots and individual sleeping areas to minimize stress-induced conflicts.

Feeding and Diet

Blue Tangs primarily feed on small crustaceans such as krill, mysis, and artemia, but their diet should be supplemented with algae-based foods like seaweed and spirulina. Ensuring they receive a diverse range of frozen foods while prioritizing algae-based nutrition is essential for their overall health and immune system support.

Habitat and Distribution

In their natural habitat, Blue Tangs are found in the Indo-Pacific region, ranging from East Africa to southern Japan, including areas like the Mascarene Islands, the southern Great Barrier Reef, New Caledonia, and Samoa. Their distribution reflects their preference for tropical marine environments with ample access to algae-rich habitats for feeding and shelter.
