Description
The Filefish is a unique saltwater fish species known for its unusual shape and vibrant colors. It is characterized by its elongated body, small mouth, and large dorsal fin. 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.
Reef Safe
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.
Behavior
Filefish are generally peaceful but can be territorial. They are known for their curious nature and will often explore their surroundings. They can also change their color and pattern to blend in with their environment, which can be a fascinating behavior to observe.
