Scrawled Filefish

Scrawled Filefish (Aluterus scriptus)

The Scrawled Filefish (Aluterus scriptus) is a fascinating species renowned for its vibrant and intricate appearance. Found in tropical and subtropical waters across the globe, including the Atlantic, Pacific, and Indian Oceans, this filefish is easily recognizable due to the striking blue and green patterns that “scrawl” across its elongated body. These fish often inhabit coral reefs, lagoons, and rocky coastal areas, where their unique colorations help them blend into their surroundings, providing camouflage from predators.

Growing up to three feet in length in the wild, the Scrawled Filefish is one of the largest filefish species. It is notable for its long, flattened body, dorsal spines, and a tail covered with small spines for protection. While its size makes it an eye-catching addition to large aquariums, it is best suited to tanks that are at least 180 gallons or larger. Like other filefish, it has a relatively slow and deliberate swimming style, which can make it a peaceful addition to an aquarium if housed with other non-aggressive species.

The diet of the Scrawled Filefish primarily consists of algae, sea grasses, sponges, and small invertebrates in the wild. In captivity, they thrive on a varied diet that includes marine algae, krill, mysis shrimp, and other meaty foods. They also have a known penchant for nibbling on soft corals, making them unsuitable for reef tanks. These fish require frequent feedings to maintain their vibrant color and health, typically two to three times daily.

Due to their size and dietary needs, the Scrawled Filefish is recommended for experienced aquarists who can provide the space and resources needed for their care. When properly cared for, these fish can live up to 7 years or more in captivity, providing a long-lasting and colorful presence in any saltwater aquarium.
