Overview:

The Convict tang is yet another beautiful species of tang. This species is not the hardest of tangs and is much smaller than all other species. It is therefore not advised for the beginner hobbyist. Look for signs of external parasites and avoid specimens that are abnormally thin or weak. Your aquarium needs to have a large filtration system; due to this species feeding patterns it produces high amounts of waste. It is advisable to use lots of biological filtration such as live rock to keep ammonia levels low. It is also important to have good water circulation to keep oxygen levels high and to allow outgassing of carbon dioxide. Running in-line mechanical filtration aids in filtering detritus, but filters must be cleaned regularly. Aim for a pH above 8.1 during the daytime. Nitrate should be kept below 20 parts per million through water changes or use of a refugium. Another especially helpful piece of equipment is an ultraviolet (UV) sterilizer or ozoniser. This will help clear aquarium water and can reduce the risk of disease.
