Harlequin Tusk

The Harlequin Tuskfish (Choerodon fasciatus) is one of the most iconic and visually striking wrasses in the marine aquarium hobby, famous for its electric blue tusks, bold banding, and confident personality.** Despite its fierce appearance, it’s generally a well‑behaved predator that thrives in large, stable reef‑adjacent or FOWLR systems. 🐠 Identity & Appearance Scientific name: Choerodon fasciatus Common names: Harlequin Tusk, Tuskfish Adult size: 8–10 inches Coloration: Alternating orange‑red and white bands, neon‑blue edging on fins, and unmistakable bright blue tusks used for crushing shells. Regional variation: Australian tusks — deeper coloration, thicker blue margins, calmer temperament. Indo‑Pacific tusks — slightly paler, more variable behavior. 🌍 Natural Habitat Range: Australia, Indonesia, Philippines, Papua New Guinea, Solomon Islands. Environment: Coral reefs, rubble zones, and lagoon slopes with abundant hiding spaces. Behavior in nature: Solitary predator that hunts crustaceans and mollusks among rockwork. 🧠 Temperament & Behavior Temperament: Confident, bold, and generally peaceful toward dissimilar fish. Aggression: Low to moderate; may bully small or timid tankmates. Reef safety: Not reef‑safe — will eat shrimp, crabs, snails, and other inverts. Personality: Intelligent, curious, and often interactive with keepers. 🏡 Aquarium Requirements Minimum tank size: 120 gallons (larger preferred for adults). Aquascape: Heavy rockwork with caves and tunnels Open swimming space Secure lid — tusks are strong but they can jump when startled Water parameters: Temp: 74–80°F pH: 8.1–8.4 Salinity: 1.023–1.025 Nitrate: <20 ppm Flow: Moderate; avoid blasting their preferred hiding zones. 🍽️ Diet Type: Carnivore — specialized shell‑crusher. Foods: Clam, mussel, shrimp, squid Mysis and krill High‑quality marine carnivore pellets Feeding frequency: 1–2 hearty meals daily. Note: A varied diet prevents nutritional gaps and keeps tusk coloration vibrant. ⚠️ Care Notes Invertebrate safety: Will consume nearly all crustaceans and snails. Tankmates: Best with medium‑to‑large semi‑aggressive fish (tangs, angels, triggers, groupers). Acclimation: Australian specimens acclimate more easily and ship better. Longevity: Often lives 10+ years in stable systems. ⭐ Why It Stands Out Electric blue tusks and vivid banding Bold, interactive personality Hardy once established Excellent centerpiece fish for large FOWLR displays
