Common name: Elongate Unicornfish
General Information
The Elongate Unicornfish, scientifically known as Naso lopezi, is a striking marine fish known for its elongated body. This species is a part of the surgeonfish family, Acanthuridae, and is admired for its unique appearance and active swimming behavior. Unlike some of its more colorful relatives, Elongate Unicornfish sports a more subdued color palette, primarily consisting of grays and blues, which gives it an elegant and sophisticated look.
In the aquarium trade, Naso lopezi is appreciated for its peaceful nature and ability to adapt to a community tank setting. It is suitable for larger aquariums due to its potential size and active swimming needs. This species is not as commonly kept as other tangs, making it a unique addition for enthusiasts looking to diversify their collections.

Taxonomy
Care
Elongate Unicornfish requires a spacious tank with ample swimming space, ideally with a volume of at least 500 liters. They thrive in aquariums that mimic their natural reef habitat, complete with live rock and open areas for swimming. While they are generally hardy, maintaining stable water conditions is crucial for their health.
Diet and Feeding
In the wild, Naso lopezi primarily grazes on algae, making it an excellent choice for controlling algae growth in the aquarium. In captivity, they should be provided with a varied diet consisting of marine-based algae, spirulina, and high-quality herbivore pellets. Supplementing their diet with occasional meaty foods like mysis shrimp can help ensure balanced nutrition.
Feed them small amounts multiple times a day to mimic their natural grazing habits. This approach helps maintain their energy levels and supports their active lifestyle.
Behavior and Compatibility
Known for its peaceful temperament, Elongate Unicornfish is generally compatible with a variety of tank mates, including other peaceful fish species. However, they can become territorial towards other tangs, especially if space is limited. Providing a large tank can help mitigate potential aggression.
Symbiosis
While Naso lopezi does not form symbiotic relationships like clownfish with anemones, its role in the aquarium can be seen as beneficial due to its algae-eating habits, which help maintain a clean tank environment.
Health and Common Issues
Elongate Unicornfish is susceptible to common marine diseases such as ich and marine velvet. Quarantining new additions and maintaining high water quality are essential preventive measures. Regular monitoring for signs of stress or disease will help ensure early detection and treatment.
Habitat
Naso lopezi is native to the coral reefs of the Indo-Pacific region. They are typically found at depths ranging from 5 to 30 meters, where they graze on algae-covered substrates. Their natural habitat is characterized by clear, warm waters and abundant coral formations, which provide both food and shelter.
