How does the primary food source for *Zebrasoma flavescens* directly link the species to areas with specific water conditions?
Answer
The need for photic zone sunlight to allow algae to flourish on hard surfaces.
The Yellow Tang’s diet is centered almost exclusively on algae, specifically turf algae which they scrape from hard surfaces. This dietary dependence necessitates that they inhabit areas where sunlight penetration is sufficient to support photosynthesis—the photic zone—allowing the algae to flourish continually. Furthermore, good water flow is mentioned as correlating with replenished food sources. This direct tie means that the spatial location of the fish is inextricably linked to the presence of well-lit, hard substrates where their energy source is consistently available for grazing.
