Filefish

Filefish, a diverse group of bony fish, are recognized for their laterally flattened bodies, small mouths, and distinctive, erectable spines on their dorsal fins. Found in a variety of marine environments, including coral reefs, seagrass beds, and open waters, these fish exhibit a wide range of colors and patterns. Many filefish species have the remarkable ability to change their appearance, camouflaging seamlessly with their surroundings to avoid predators. Their velvety or sandpapery skin texture, caused by tiny dermal spines, adds to their unique tactile quality.

Filefish are known for their varied diet, which can include algae, seagrass, small invertebrates, and even corals, depending on the species. They are generally sluggish swimmers, often drifting among seaweed or retreating into crevices when threatened, a behavior that aids in their concealment. Due to their distinct physical features and interesting behaviors, filefish are occasionally kept in aquariums. However, not all species are considered reef-safe, as some may nip at corals or display territorial aggression, requiring careful selection and monitoring in captivity.
