Here are some intriguing details about the Yellow Tang:
-
Appearance: Adult Yellow Tangs grow to approximately 20 centimeters (7.9 inches) in length and 1–2 centimeters (0.39–0.79 inches) in thickness. They exhibit a vibrant yellow hue during the day, which fades slightly at night. A prominent brownish patch develops in the middle, accompanied by a horizontal white band. Their dorsal spines and soft rays, along with a white spine on the caudal peduncle, contribute to their unique appearance. When mating, males change color and exhibit a “shimmering” behavior.
-
Habitat: Yellow Tangs inhabit reefs, either alone or in small groups. They are mainly herbivorous, feeding on filamentous algae.
-
Taxonomy and Etymology: The scientific name Zebrasoma flavescens reflects its yellow color. The genus name “Zebrasoma” refers to the zebra-like stripes or bars on its body. Interestingly, within the genus, the Yellow Tang forms a species pair with the Scopas Tang (Z. scopas).
-
Reproduction: Yellow Tangs spawn throughout the year, with peak activity occurring around the full moon. Lunar periodicity likely plays a role in their reproductive cycle.
-
Defense Mechanism: To protect itself, the Yellow Tang possesses a white spine just before its tail fin. It can use this spine for defense by swimming backward and jabbing its enemies.
In summary, the Yellow Tang adds a vibrant splash of color to coral reefs, captivating both aquarists and ocean enthusiasts alike.
