Filefish- Green
The Green Filefish (Acreichthys tomentosus), also known as the Matted Filefish, is a unique and colorful fish species known for its ability to change colors and mimic its surroundings. Here are the general requirements for keeping a Green Filefish:
Tank size: Green Filefish can be kept in a tank with a minimum capacity of 30 gallons (113 liters). However, a larger tank is recommended if you plan to keep them with other tankmates or want to provide more swimming space. They are relatively small and do not require a massive tank.
Tank setup: Provide a well-decorated tank with plenty of hiding places and live rock. Green Filefish appreciate the presence of caves, crevices, and rockwork that mimic their natural habitat. They may also use the rockwork as a grazing surface. Ensure the tank has open swimming areas as well.
Water parameters: Maintain stable and pristine water conditions. The recommended water temperature for Green Filefish is between 72°F and 78°F (22°C - 26°C). The pH should be maintained between 8.1 and 8.4, and the salinity level (specific gravity) should be within the range of 1.020 to 1.025. Regular monitoring of water parameters, efficient filtration, and regular water changes are important for their well-being.
Lighting: Green Filefish do not have specific lighting requirements. Providing moderate lighting that replicates their natural reef environment is generally suitable. However, if you have corals or other photosynthetic organisms in the tank, consider their lighting needs as well.
Feeding: Green Filefish are primarily herbivorous and require a diet rich in algae and other plant-based foods. Provide a variety of marine-based algae, such as dried seaweed or marine algae sheets. They may also accept some prepared herbivorous aquarium foods, such as pellets or flakes specifically designed for herbivorous fish. Supplement their diet with occasional small amounts of meaty foods, such as frozen or live brine shrimp or mysis shrimp.
Tankmates: Green Filefish are generally peaceful but can be territorial towards their own species or other similar-looking fish. It's best to keep them as the only Green Filefish in the tank. They can generally coexist with other peaceful and non-aggressive fish species that are not similar in appearance or body shape. Avoid keeping them with aggressive or fin-nipping tankmates.
Acclimation: Proper acclimation is crucial when introducing a Green Filefish to a new aquarium. Slowly drip acclimate the fish to the water parameters of your tank over a period of time to reduce stress and help them adjust to their new environment.
Green Filefish are generally hardy and adaptable, making them suitable for beginner and intermediate aquarists. However, it's important to provide suitable hiding places, maintain stable water conditions, and offer a balanced diet to ensure their long-term health and well-being.
