The Green Filefish, often referred to as the Bristletail or Tassel Filefish in its various forms, is a high-utility master of camouflage. Featuring a cryptic, olive-to-emerald green body that can shift in intensity based on its surroundings, this fish is designed to blend seamlessly into macroalgae and seagrass beds. In the "Answering Machine" era of saltwater husbandry, the Green Filefish is frequently employed as a biological solution for nuisance pests, though it is just as easily kept for its unique "prehistoric" appearance and hovering swimming style.
With its independent eye movement and a retractable dorsal spine, the Green Filefish is a constant source of visual interest. It is a slow, methodical swimmer that spends its time investigating the rockwork, adding a calm and inquisitive presence to the aquarium.

Quick Specs
Care Level: Easy
Temperament: Peaceful
Minimum Tank Size: 30 Gallons
Diet: Omnivore
Reef Compatible: Yes (With Caution—may nip at small polyps or xenia)
Max Size: 4 Inches
Water Conditions: 72-78°F, dKH 8-12, pH 8.1-8.4, sg 1.020-1.025
Husbandry Notes The Green Filefish is an adaptable eater that thrives on a varied diet of meaty marine foods like mysis shrimp and chopped krill, supplemented with algae-based flakes or pellets. In many reef systems, they are introduced specifically to control Aiptasia populations, though their effectiveness can vary between individuals. While generally peaceful toward tank mates, they should be monitored in reef tanks as they may occasionally nip at soft corals or zoanthids if underfed. They appreciate an environment with plenty of rockwork and macroalgae to mimic their natural habitat.
