Black tang 6-7” (Zebrasoma rostratum)

The Black Tang is one of the most rare and highly sought-after surgeonfish in the marine aquarium hobby, prized for its deep velvet-black coloration and elegant body shape. Endemic to the Pacific Ocean, primarily around the Line Islands, this striking species can reach an adult size of 8–10 inches and requires a large, mature saltwater aquarium with ample swimming space.

The Black Tang is a herbivorous grazer, thriving on a diet of marine algae, nori, spirulina-based foods, and high-quality pellets or flakes. It has a generally peaceful to semi-aggressive temperament, becoming more territorial toward other tangs, especially similar-shaped species. Reef safe with corals, it plays a beneficial role in algae control within reef and FOWLR systems.

Hardy once acclimated and visually unmatched, the Black Tang is ideal for experienced aquarists seeking a rare, high-end centerpiece fish for large reef or fish-only aquariums.
