Desjardini Sailfin Tang
Species: Zebrasoma desjardinii
Growth Form:
Marine surgeonfish known for its tall, sail-like dorsal and anal fins that expand dramatically when fully extended. The body is laterally compressed, giving it a distinctive disk-shaped appearance.
Coloration:
Juveniles display striking horizontal striping with golden and brown tones. As they mature, the body develops a complex pattern of spots and lines with earthy browns, creams, and yellows. The fins often feature beautiful spotted patterns that become more pronounced with age.
Temperament:
Semi-aggressive. Generally peaceful toward most tankmates but can become territorial toward other tangs or similarly shaped fish. Best kept singly unless housed in very large aquariums.
Tank Size:
180 gallons and up.
This species grows large and requires significant swimming space and strong water movement.
Placement:
Active swimmer that utilizes the entire water column. Provide plenty of open swimming space along with ample rockwork for grazing and shelter.
Lighting:
Moderate to high reef lighting. Lighting primarily supports algae growth within the aquarium, which forms part of the tang’s natural diet.
Flow:
Moderate to strong flow.
Prefers well-oxygenated water with good circulation, similar to reef environments in the wild.
Diet:
Primarily herbivorous. Feeds on algae and marine vegetation in the wild.
Feeding:
Offer a varied diet including marine algae, nori, spirulina-based foods, herbivore pellets, and occasional mysis shrimp or brine shrimp. Frequent small feedings help maintain health and coloration.
Reef Safe:
Yes. Generally safe with corals and invertebrates, though it may graze on nuisance algae throughout the tank.
Care Level:
Moderate.
Best suited for aquarists with larger aquariums and experience maintaining stable marine systems. Requires excellent water quality and ample swimming space.
Ideal Parameters:
-
Salinity: 1.024–1.026
-
Temperature: 75–79°F
-
pH: 8.1–8.4
-
Nitrates: <20 ppm
-
Strong oxygenation and stable parameters recommended
Fun Fact:
The Desjardini Tang is often called the “Indian Ocean Sailfin Tang.” When threatened or displaying dominance, it dramatically flares its large fins, making the fish appear much larger to potential rivals.
