Comparison Table 

Sailfin Tang (Zebrasoma veliferum)

Appearance

The Sailfin Tang is easily recognized by its dramatic appearance. It features a dark brown body adorned with bright yellow and white stripes. The most distinctive aspect of its appearance is the elongated dorsal and anal fins, which expand like sails when the fish feels threatened or excited. These fins are typically covered with the same striking stripes that cover the body, enhancing its visual appeal.

Size

In the wild, Sailfin Tangs can grow up to 15 inches, but in captivity, they typically reach around 12 inches. Their size makes them a significant aquarium presence, requiring ample space to thrive.

Temperament

Sailfin Tangs are semi-aggressive, particularly towards other tangs. They establish territories and can become combative if their space is encroached upon. Monitoring their behavior is essential, especially in tanks with multiple tangs or large territorial fish.

Habitat

Native to the Indian Ocean and South Pacific, Sailfin Tangs inhabit coral-rich areas of reefs and lagoons. In captivity, they require a tank with plenty of hiding spots, live rock for grazing, and open swimming areas. A tank size of 125 gallons is recommended to accommodate their active lifestyle.

Diet

Primarily herbivorous, Sailfin Tangs feed on algae. In an aquarium, their diet should include a variety of vegetable-based foods, such as spirulina, seaweed, and high-quality flake foods designed for herbivores. Regular feeding of marine algae or seaweed is crucial for their health and coloration.

Suitable Tank Mates

Sailfin Tangs do well with peaceful fish that won’t challenge their territory. Ideal tank mates include gobies, blennies, and reef-safe invertebrates like cleaner shrimp. Avoid housing them with other tangs to prevent territorial disputes unless the tank is huge.

Care Level

Moderate. While not the most challenging species to care for, Sailfin Tangs require stable water conditions and a well-maintained environment. They are best suited for aquarists with some experience keeping saltwater fish.​

Yellow Tang (Zebrasoma flavescens)

• Appearance and Size: The Yellow Tang is easily recognizable by its bright yellow, oval-shaped body. They grow to about 8 inches, making them smaller than Sailfin Tangs.
• Tank Requirements: A minimum of 100 gallons is recommended for Yellow Tangs. They need plenty of swimming space and live rock for grazing.
• Diet: Like Sailfin Tangs, Yellow Tangs are herbivorous and require a diet rich in marine algae. It is essential to feed them dried seaweed and algae-based foods at least three times a week.
• Behavior: Yellow Tangs are relatively hardy and peaceful but can exhibit territorial aggression, especially towards other tangs. It is best to keep just one Yellow Tang unless introduced simultaneously in a large tank ​.

Purple Tang (Zebrasoma xanthurum)

• Appearance and Size: Purple Tangs are striking with their deep purple color and vivid yellow tail. They typically reach about 9 inches in length.
• Tank Requirements: Purple Tangs require a minimum of 100 gallons but will benefit from larger tanks to reduce stress and aggression. They need a balance of open swimming space and structures like live rock for hiding and grazing.
• Diet: Purple Tangs are herbivores that graze on filamentous algae. Supplementing their diet with nori and other seaweed is crucial to maintain their health and vibrant color.
• Behavior: These tangs can be semi-aggressive, especially in smaller tanks. They are reef-safe and often found in groups in the wild, but in captivity, they should be kept singly unless the tank is huge​.

Convict Tang (Acanthurus triostegus)

• Appearance and Size: Convict Tangs have a distinctive pattern of vertical black stripes on a white or grey body, resembling a prison uniform. They grow to about 8 inches.
• Tank Requirements: A minimum of 125 gallons is recommended for Convict Tangs. They are active swimmers and need ample space to move around.
• Diet: As herbivores, Convict Tangs feed on algae. It is essential to provide them with plenty of marine-based algae and seaweed.
• Behavior: Convict Tangs are relatively peaceful and can be kept in groups if the tank is large enough. They are less aggressive than other tang species, making them a good choice for community tanks​.
