Care
Caring for the Orange-Striped Pygmy Filefish requires attention to detail due to its specific dietary and environmental needs. This species thrives in a well-established aquarium with plenty of live rock for grazing and hiding. They are generally peaceful but can be territorial towards conspecifics, so it's advisable to keep only one per tank unless the aquarium is large enough to support multiple territories. A varied diet of meaty foods, such as mysis shrimp and finely chopped seafood, supplemented with marine algae, will help maintain their health and coloration.
Reproduction
In the wild, Pervagor aspricaudus exhibits a monogamous breeding behavior, with pairs forming strong bonds. In captivity, breeding is less common, but with the right conditions, including stable water quality and a stress-free environment, it is possible. The male typically guards the territory while the female deposits eggs, which the male then fertilizes.
Habitat
Native to the Indo-Pacific region, the Orange-Striped Pygmy Filefish is often found in coral-rich areas and lagoons. They prefer shallow waters where they can easily access food sources and shelter among the corals and rocks. Their natural habitat includes regions from the Red Sea to South Africa, east to the Line, Marquesan, and Society islands, north to southern Japan, and south to New Caledonia.
