General Description
The Redtail filefish, also known as Lace-finned leatherjacket, Blackheaded filefish, Black-headed leatherjacket, Black-head filefish, or Redtail filefish, belongs to the Monacanthidae family, specifically the Pervagor genus. With a maximum size of 16.0cm, these fish have a characteristic appearance that divides opinions; however, some species can adapt to aquarium life. This species is indigenous to the Indo-West Pacific region.
Aquarium Suitability
Considered suitable for aquariums, the Redtail filefish requires care due to their potential threat towards small crustaceans like shrimp. They possess an average level of hardiness and prefer a tank size of at least 600 liters. When introducing them to a tank, it is crucial to ensure a peaceful environment to aid their adjustment.
Care and Hardiness
These fish are docile and shy, emphasizing the need for caution when housed with more aggressive tank mates. Redtail filefish require enriched food to maintain their vibrant coloration and frequent feeding, especially upon initial introduction. Providing hiding spots like live rocks is essential for their well-being.
Reef Suitability
Reef compatibility with the Redtail filefish can be achieved with luck, as they may exhibit aggressive behavior towards similar species. They are known to eat tubeworms and glass anemones, although individual preferences for these foods can vary.
Aquarium Setup
When setting up an aquarium for the Redtail filefish, it is recommended to include ample hiding places like live rocks. Maintaining water conditions within the parameters of pH 8.1-8.4, specific gravity of 1.020-1.025, carbonate hardness of 8-12, and a temperature range of 22.2-25.6 degrees Celsius is crucial for their well-being.
Behaviour
The Redtail filefish are mostly peaceful but can exhibit aggression towards similar species. They may initially face challenges in accepting commercially available fish food, so luring them with live prey like shrimp can aid in their acclimation.
Feeding and Diet
Their recommended diet consists of larger crustaceans like shrimp and crabs, macroalgae such as seaweed or nori, microalgae like spirulina, and small crustaceans including krill, mysis, and artemia. Ensuring a varied diet is essential for their nutritional needs.
Dimorphism
Captive reproduction information for the Redtail filefish is not available, and specific details on dimorphism remain unspecified.
Habitat and Distribution
The Redtail filefish's natural habitat spans the East Indian Ocean, West Indian Ocean, Australia, Japan, Indonesia, the East Pacific, and Central/West Pacific regions. In their natural environment, they help control populations of glass anemones like Aiptasia.
