⚠️ Important Information — Please Read First
We want to be genuinely upfront on this one. Due to a genuine suspension of aquarium collecting around Hawaii that began in early 2021, demand and pricing for this species has genuinely increased substantially, and today's supply is largely sourced from other Pacific regions or successful captive-breeding programmes such as the Oceanic Institute. This species genuinely requires a real, spacious tank of at least 100-125 gallons, given its constant, active swimming nature.
📋 The Yellow Tang, also known as the Yellow Hawaiian Tang, Yellow Sailfin Tang, or Yellow Surgeonfish, has a genuinely brilliant, solid yellow oval body that has made it, for many aquarists, the single most definitive and recognisable fish in the entire saltwater hobby.
Native to a genuinely wide swath of the Pacific Ocean, from the Philippines through southern Japan, the Marshall Islands, and Hawaii, this species is genuinely most iconic to and commonly associated with Hawaiian reefs, where its Hawaiian name, lau'īpala, genuinely translates to "yellowed ti leaf."
We want to share a genuinely charming fact: this species' bright yellow colouration genuinely fades to a duller, paler shade at night while sleeping, a real phenomenon that has understandably startled many new keepers checking on their tank in the morning — rest assured, the colour returns to normal shortly after the lights come on. This is genuinely a hardy, active swimmer that spends nearly all its time in near-constant motion, and it does show genuine territorial aggression toward its own species or other tangs, particularly those of a similar body shape. It's fully reef safe, and genuinely a voracious, valuable algae grazer, requiring a real varied herbivorous diet to thrive.
