The Filefish is also known for its ability to change color and pattern to blend with its surroundings, making it a fascinating addition to any aquarium.

Filefish are considered reef safe with caution. They may nip at soft and stony polyp corals as well as certain invertebrates.
Environment
Filefish prefer a tank with plenty of hiding spots and swimming space. They thrive in tanks with a lot of live rock for grazing and hiding. The tank should have a tight-fitting lid to prevent them from jumping out.
