What is the typical maximum depth range where Yellow Tangs are commonly observed utilizing tropical reef environments?
Answer
Down to about 45 meters (approximately 148 feet)
Yellow Tangs are strongly associated with shallow, tropical reef environments, but they utilize a specific vertical range within these areas. Their preferred depths generally extend from the surface area down to approximately 45 meters, which is equivalent to about 148 feet. This depth range keeps them firmly within the photic zone, which is crucial because their primary food source, algae, requires sunlight to flourish on the hard surfaces of the reef substrate. Habitats shallower than this are also utilized, especially along exposed reef crests during feeding periods, but 45 meters represents the general limit of their typical observation depth.
