Zebrasoma desjardinii
The Desjardin’s Sailfin Tang, also known as the Red Sea Sailfin Tang, is a striking and large species of surgeonfish. Its body is a beautiful mix of brown and yellow, adorned with intricate, wavy blue lines that run horizontally along its flanks. The dorsal and anal fins are exceptionally tall and sail-like, especially when extended, displaying a similar pattern of blue lines on a brown background. The tail fin is typically yellow with a blue edge.
A minimum tank size of 180 gallons is recommended for this species due to its potential large size and active swimming habits. A mature aquarium with ample live rock for grazing on algae and plenty of open swimming space is essential for its well-being. While generally peaceful towards most tank mates, they can be aggressive towards other tangs, especially those of similar size or shape. Introducing them as the last fish in the tank can help minimize aggression.
The Desjardin’s Sailfin Tang is primarily a herbivore, and a significant portion of its diet should consist of marine algae. Offer dried seaweed (nori) attached to a rock or clip multiple times a day. Supplement their diet with high-quality marine pellets and flakes, as well as occasional offerings of mysis shrimp or other meaty foods. A varied diet is crucial for maintaining their vibrant colors and overall health. They can reach a size of up to 16 inches in the aquarium. There are no readily apparent visual differences between males and females.
