Bluetail Unicornfish - Naso caeruleacauda

The **Bluetail Unicornfish** is a prominent member of the surgeonfish family, known for its impressive size and striking appearance. This species features a predominantly silver-gray body accentuated by a vivid blue tail. First described by J.E. Randall in 1994, the **Bluetail Unicornfish** thrives in the coral reefs of the Philippines and Indonesia.

Reaching up to 24 inches, these robust swimmers require spacious environments, ideally in aquariums of at least 200 gallons. Generally peaceful, the **Bluetail Unicornfish** coexists well with corals and invertebrates, making it a great choice for large reef setups. However, caution is advised when housing them with other tangs, particularly those from the Naso family, as they can exhibit territorial behavior. Ensuring ample algae and a larger tank can help mitigate aggression.

To mimic their natural habitat, provide a tank with strong, varied water flow. As natural grazers, **Bluetail Unicornfish** need constant access to algae, best achieved with well-established live rock. They often claim rock formations as their territory.

As herbivores, their diet should be rich in greens, including marine algae sheets, nori, brine shrimp, mysis, high-quality flakes, pellets, and spirulina. This balanced diet ensures the **Bluetail Unicornfish** remains healthy and vibrant.
