Temperament
Description
A silvery-white to pale yellow surgeonfish marked with five to six narrow vertical black bars and a small black smudge above the pectoral fin; its caudal peduncle scalpels are notably smaller than those of most tangs. One of the more peaceful, hardier tangs, it grazes constantly on filamentous algae and needs a long, open swimming lane with strong flow and high oxygenation, plus rockwork for grazing and refuge. Keep it singly or as a simultaneously introduced group in large systems, and avoid housing it with other tang species, which tend to bully it.
Reef Safe
Yes
Environment
Convict Tangs thrive in a well-lit aquarium with plenty of live rock for grazing and hiding. They prefer a strong current and high-quality water conditions.
Behavior
Convict Tangs are active and social fish. They are known to be peaceful but can become territorial and aggressive if the tank is too small or overcrowded. They are also known to be jumpers, so a well-fitted tank lid is necessary.
