Yellow Tang

Small Yellow Tang 1-3" overallThe Biota Captive‑Bred Yellow Tang (Zebrasoma flavescens) is a hardy, sustainably produced surgeonfish that adapts far better to aquarium life than wild‑caught specimens, making it one of the most reliable tang options for reef keepers. Below is a clear, shop‑ready overview grounded in current, authoritative sources. 🐠 Species Identity & Origin • Scientific name: Zebrasoma flavescens • Type: Captive‑bred, produced by Biota in partnership with the Oceanic Institute of Hawai‘i Pacific University. • Why it matters: Captive‑bred Yellow Tangs settle more easily, experience less transport stress, and represent the sustainable alternative after Hawaii’s collection ban. 🎨 Appearance & Size • Coloration: Bright, uniform yellow; captive‑bred juveniles deepen in color as they mature. • Juvenile size: ~1.25 inches at sale. • Adult size: Up to 8 inches. 🧠 Behavior & Temperament • Temperament: Semi‑aggressive toward other tangs or similar‑shaped fish; peaceful with dissimilar species. • Territoriality: Strong; best kept singly unless in very large (6‑ft+) systems with careful introduction. • Activity: Constant grazer and active swimmer; requires open space. 🏡 Aquarium Requirements • Minimum tank size: • Juveniles: can begin in smaller systems • Adults: 125 gallons+ recommended. • Environment: • High‑oxygen, high‑flow reef systems • Ample rockwork for grazing and territory • Acclimation: Captive‑bred individuals acclimate quickly; many aquarists use acrylic acclimation boxes for 7+ days when mixing tangs. 🍽️ Diet & Feeding • Primary diet: Herbivore—requires algae‑rich foods. • Recommended foods: • Nori • Spirulina brine • TDO C1/C2 pellets • DKI pellets • Masstick • Mixed frozen herbivore blends • Avoid: Diets high in meaty or high‑protein foods. 🧬 Hardiness & Lifespan • Captive‑bred advantage: Lower stress, fewer health issues, and better long‑term survival than wild‑caught fish. • Lifespan: • Wild: up to 30–40 years • Captivity: typically 10–20 years with proper care 🪸 Compatibility • Reef‑safe: Yes—excellent algae grazer. • Caution: Aggressive toward other tangs, especially Zebrasoma species (e.g., Black, Gem). 🌱 Sustainability Notes • Biota’s program represents the first successful commercial aquaculture of Yellow Tangs, a major milestone for the hobby.
