Naso Tang

About this fish

Naso Tang is a saltwater tang from the genus Naso (scientific name: Naso lituratus). In a home reef aquarium, this active grazer is typically used to help keep algae under control while adding a bold, swimming presence to the display. Because tangs are constantly active and need adequate space to swim and graze, the Naso Tang is best suited to established, well-maintained tanks with room for open water.

Features:

• Active, open-water swimmer that grazes algae throughout the day
• Best kept with plenty of swimming space in a long tank
• Feeds readily on algae sheets and seaweed, with additional options like frozen and pellet foods
• Has a sharp spine near the tail; handle carefully and avoid sudden size/presence changes
• Can be territorial with other tangs, so plan tankmates thoughtfully
• Generally considered reef compatible with corals when aquarium conditions and feeding are appropriate
• Arrives best with slow acclimation to reduce stress, then a calm period to settle in
