Yellow Tang
Zebrasoma flavescens
Water Parameters
About
The Yellow Tang is one of the most iconic and popular marine fish. Its uniform bright yellow with a white caudal spine is unmistakable. It is an excellent algae grazer, helping to keep the aquarium clean. Primarily from Hawaii, recent collection restrictions have significantly increased its price.
Behavior & Temperament
Active, herbivorous fish that continuously grazes algae in the aquarium. Semi‑aggressive toward other tangs and fish of similar shape or color. Possesses a sharp white caudal spine.
Feeding
Herbivore. Primarily plant-based diet: nori algae, spirulina, algae-based flakes, cooked vegetables (broccoli, spinach). Supplement with mysis and brine shrimp occasionally.
Breeding
Oviparous. Spawns pelagically in groups. Does not breed in home aquariums. Captive breeding research has progressed significantly.
Care Notes
A vegetable-rich diet (nori, spirulina) is essential for health and coloration. Provide a large tank with live rock for grazing. Quarantine is recommended before introduction. The caudal spine can cause cuts.
Compatibility
Excellent algae controller in reef tanks. Can be aggressive toward tangs of similar color or shape. Compatible with most reef fish. Introduce last.
