The Orange Line Chromis, Acanthochromis polyacanthus, also known as the Spiny Chromis, features a stark transition from its juvenile to adult stages. As a juvenile, the Orange Line Chromis features a blueish body with a broken orange horizontal line from its gills to its tail. As an adult, its color becomes more brown and it develops a white tail.
The Orange Line Chromis is incredibly hardy, easy to care for, peaceful, and will thrive in almost any aquarium environment. They are one of the best schooling species and can be kept in large groups. Additionally, they are long lived and can have a life span of up to 15 years if cared for properly and in aquariums with good water quality.
They are best kept in tanks of at least ten gallons with plenty of live rock work and should be fed an omnivorous diet. If multiple individuals are desired, it is best to add them all at the same time to avoid any territorial aggressions.
