Desjardini

The Desjardini tang (Zebrasoma desjardinii) is a saltwater fish with a deep body, large fins, and a striking color pattern: 

• Size: Males can grow to be around 16 inches long. 
• Body shape: Oval-shaped with a deep body that's 1.8 to 2 times its depth. 
• Fins: Large, sail-like dorsal and anal fins. The dorsal fin has 4 spines and 27 to 31 soft rays, while the anal fin has 2 spines and 22 to 24 soft rays. 
• Color: Deep blue with yellowish-orange horizontal stripes, white polka dots on the face, and dark grey vertical bars with orange or yellow vertical lines. 
• Tail: Dark and spotted. 
• Scalpel: A razor-sharp spike located at the base of the tail that's nearly invisible when it's flat. 
• Behavior: Generally peaceful and gets along well with other fish, but can be aggressive towards its own species. 
• Diet: Herbivore that eats filamentous algae, flake food, frozen food, and live food. 
• Habitat: Well-established aquariums with plenty of swimming space and hiding spots among live rock formations. 

Desjardini tangs from the Indo-Pacific region are typically larger and have a more brilliant color palette than those from the Red Sea.
