Convict Tang (Acanthurus triostegus)

Max Size: 8 inches
Diet: Herbivore
Temperament: Semi-Aggressive
Reef Compatible: Yes
Minimum Tank Size: 125 gallons

The Convict Tang, also known as the Convict Surgeonfish, boasts an exquisite white to silver body adorned with six vertical black bars, creating a captivating appearance. Unlike other Tangs, its peduncle spines near the tail are relatively small. This striking fish makes a wonderful addition to both reef and fish-only aquarium setups.

Given its need for ample space to swim, a sizable aquarium of at least 125 gallons is essential for the Convict Tang. It's crucial to avoid housing it with other species of Tangs, as they may harass it. However, if multiple Convict Tangs are introduced to the tank simultaneously, they can coexist peacefully.

Distinguishing between male and female Convict Tangs is quite challenging, as they lack distinguishing characteristics. Breeding them in an aquarium setting is also difficult because their fry remain in the planktonic stage for several months and are constantly at risk from filters.

To ensure the well-being of Tangs and foster a harmonious environment, it's vital to offer them a balanced diet. While they do consume meaty foods along with other fish in the aquarium, providing marine-based seaweed and algae is essential. This dietary addition strengthens their immune system, reduces aggression, and promotes overall health. You can provide dried seaweed tied to a rock or use a veggie clip to ensure they have access to these crucial nutrients at least 3 times per week. Excellent products such as Sea Veggies, Seaweed Salad, and Ocean Nutrition are available and straightforward to use for this purpose.
