Keeping notes
- 1Needs tank length; adults reach 15-20 cm and fade in cramped tanks.
- 2The white tail spines are weapons and snag in nets; use a container instead.
- 3Herbivore: supply nori and algae sheets long term or it wastes away.
- 4Reef safe and a frontline grazer against hair algae.
- 5Fights with congeners; keep one, or add several at the same time.

Frequently asked questions
- How big does Yellow Tang get?
- Yellow Tang reaches an adult standard length of 15–20 cm (excluding the caudal fin). Size the tank for that, not for the juvenile you bring home — the difference is often several times over, and upgrading later costs more than buying once.
- What water does Yellow Tang need?
- 24–27 °C, pH 8.1–8.4, 7–12 dGH, 7–9 dKH, specific gravity 1.023–1.026. That is only 3 °C wide, so stability matters more than hitting a particular number.
- What is the smallest tank for Yellow Tang?
- At least 300 L, and no shorter than 120 cm. That is the floor for long-term keeping, not for short-term survival: volume buys water stability and length buys swimming room, and neither substitutes for the other. It is not a schooling fish, so a single specimen or a pair is fine.
- What is Yellow Tang like to keep?
- Temperament: semi-aggressive. Difficulty: beginner. It occupies the all levels and is herbivore. Reef safety is "Reef safe".
- Can Yellow Tang be kept with its most common tank mate?
- The checker returns "Can be kept together". Yellow Tang and Ocellaris Clownfish is a well-established pairing. Individual fish still differ; the record says "usually fine", not "guaranteed".
