Adults display a tan to grey body with darker lines outlining the body, two prominent black markings behind the eyes and at the scalpel that are outlined in brilliant electric blue, and a forked tail that develops vivid blue and white colouration as the fish matures. The twin dark marks on the shoulder are what earn this fish its two most evocative common names: to some hobbyists they resemble the rank insignia of a military lieutenant, to others the canine teeth of a vampire. This species also undergoes a notable colour transformation from juvenile to adult; juveniles display a warm yellowish-gold colour that gradually develops into the complex adult pattern, making it a fascinating fish to grow out over time. It is a large, active, and powerful swimmer suited exclusively to spacious, mature systems.\u003c\/p\u003e\n\u003ch3\u003eWhy we love it\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eA genuinely striking and unusual-looking tang with a colour pattern that improves and deepens dramatically from juvenile to adult\u003c\/li\u003e\n\u003cli\u003eParticularly sought after for large reef aquariums where it works to keep excess algae growth in check, including hair algae, without bothering delicate corals or smaller peaceful reef fish\u003c\/li\u003e\n\u003cli\u003eActive and entertaining with a bold swimming style that uses the full water column, making it a constant presence in any large display\u003c\/li\u003e\n\u003cli\u003eFully reef safe with corals and ornamental invertebrates when well fed\u003c\/li\u003e\n\u003cli\u003eA rewarding long-term species with a lifespan that can exceed a decade in a properly maintained system\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSuggested parameters\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTemperature: 24 to 26°C (75 to 79°F)\u003c\/li\u003e\n\u003cli\u003eSalinity: 1.025 to 1.026 SG\u003c\/li\u003e\n\u003cli\u003epH: 8.1 to 8.4\u003c\/li\u003e\n\u003cli\u003eAlkalinity: 8 to 10 dKH\u003c\/li\u003e\n\u003cli\u003eCalcium: 400 to 450 ppm\u003c\/li\u003e\n\u003cli\u003eMagnesium: 1250 to 1400 ppm\u003c\/li\u003e\n\u003cli\u003eNitrate: Under 20 ppm;

Maintaining the highest possible water quality and offering a varied diet rich in nutritious marine-based algae, soaked in vitamins, is the most effective long-term defence against skin parasites and fin erosion in this species. Quarantine before introduction to a display system is strongly encouraged. A varied, algae-heavy diet begun immediately upon acclimation is critical to building a robust immune response in new arrivals.\u003c\/p\u003e\n\u003ch3\u003eWhat you are buying\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eYou will receive: 1 Tenenti Tang (Acanthurus tennenti)\u003c\/li\u003e\n\u003cli\u003eJuveniles are primarily yellowish-gold and will develop the full adult pattern of tan-grey body, twin black shoulder marks with electric blue outlines, and forked blue-and-white tail over time\u003c\/li\u003e\n\u003cli\u003eColouration and pattern definition intensify significantly with age and a strong algae-based diet\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eSlow acclimation is recommended.
