Overview
Yellow Tangs are iconic bright lemon-yellow marine fish that bring instant vibrance to a reef tank. They are active swimmers that need plenty of open horizontal space and constant access to marine algae for grazing. They can be territorial, especially toward other tangs, so provide a large tank and introduce them last when possible.

Expert Care Tips for Yellow Tang
- Large tank required: At 75+ gallons, Yellow Tang needs serious equipment investment. Ensure your filter is rated for at least 1.5× the tank volume.
- Tropical range: Keep Yellow Tang at 75–80°F. A 50W heater per 10 gallons is a safe rule of thumb for stable temperature.
- Narrow pH tolerance: Yellow Tang only tolerates pH 8.1–8.4. Test your tap water before buying — adjusting pH is harder than choosing the right fish for your water.
- Semi-aggressive temperament: Yellow Tang is generally peaceful but can become territorial. Provide ample hiding spots and avoid housing with fin-nipping species.
- Acclimation: Always drip-acclimate Yellow Tang over 30–45 minutes. Match temperature and pH gradually to prevent osmotic shock.
