Matted File Fish

Deploy the ultimate, hard-working solution for reef pest management. The Matted Filefish is globally celebrated by reef-keepers as a premium biological control agent. While it sports a subtle, mottled green and brown camouflage palette rather than bright neon colors, its quirky behavior, horizontal hovering style, and relentless work ethic make it an indispensable asset to your clean-up crew. 

When chemical treatments fail and invasive pests take over your rockwork, this hardy little worker systematically cleans your tank from the bottom up. 

The premier choice for naturally eradicating invasive Aiptasia (glass anemones) and Majano anemones. Armed with a specialized, beak-like mouth, they precisely target and consume these stinging pests from tight rock crevices before they can reproduce and crowd out your corals. 

Beyond hunting unwanted anemones, they are highly opportunistic predators that will naturally forage for small bristle worms, flatworms, and small nuisance hydroids, helping to balance your aquarium's micro-ecosystem. 

Possesses a fascinating skin texture covered in tiny, brush-like bristles (setae) that help break up its silhouette. They have the remarkable ability to rapidly shift their skin color from light tan to dark mottled green in seconds to blend seamlessly into live rock or macroalgae beds. 

Unlike finicky butterflyfish, Matted Filefish acclimate to aquarium life with ease. When they are not hunting pests, they eagerly accept standard aquarium fare. Offer a varied diet of frozen mysis shrimp, brine shrimp, chopped seafood, and high-quality marine flakes or pellets. 

While generally safe for standard SPS and hardier corals, they are curious nibblers. If they run out of pest anemones or are underfed, they may occasionally sample zoanthids, green star polyps, or the fleshy polyps of LPS corals. Keep them well-fed to minimize this behavior.
