Final answer:
The sentence provided should include a semicolon before 'the fish' as it joins two main clauses that are closely related, making the fully punctuated sentence read correctly.
Step-by-step explanation:
The correct punctuation for the sentence should include a semicolon before the word 'the' because it is used to join two main clauses that are closely related, but could stand on their own as separate sentences. Additionally, the second main clause starts with 'the fish,' which serves as a transitional phrase. So, the sentence with the correct punctuation would read as follows:
"A "fish pedicure" requires a client to soak his or her feet in a pool filled with Garra rufa fish; the fish then nibble away the dead skin from the client's feet."
In the peculiar practice of a "fish pedicure," a client immerses their feet in a pool teeming with Garra rufa fish; these aquatic creatures diligently nibble away the dead skin.
The therapeutic process, though unconventional, is believed to exfoliate and rejuvenate the feet. The juxtaposition of feet submerged in water and fish engaged in a skin-nourishing task creates a unique sensory experience.
The symbiotic relationship between client and piscine practitioners unfolds in the aquatic ambiance, where the tactile interaction of nibbling fish transforms an ordinary foot treatment into an extraordinary, albeit eccentric, form of self-care, leaving patrons with smoother, revitalized feet.
