The Convict Tang, otherwise known as the Convict Surgeonfish, is a bright white-silver with vertical brown-black stripes. Their dorsal fin can be a white or light yellow and their peduncle spine (close to the tail) is smaller than most tangs. Convict Tangs are a popular tang for reef and fish only aquariums


It is recommended to house a Convict Tang in a 125 gallon tank or larger to provide plenty of room for swimming. Convict Tangs can be a bit aggressive towards other tangs, but if you introduce them to a school of Convict Tangs all at once, it should be rather amicable. These types of tang are beneficial in picking at hair algae. They tend to spend their days picking at rock and sand, in search for hair algae to eat.



Although tangs will eat meaty foods, they prefer marine based seaweed and algae which will boosts their immune system, reduce aggression, and improve overall health. To feed them, tie dried seaweed to a rock or use a veggie clip, and feed at least 3 times per week.
